Great job, Stephan. You've just made one of the greatest video on the subject.
I tried Kitty Litter Silica Gel and my tester showed 80%+ humidity. I took some and dried it in the oven for a couple of hours and now I'm getting under 15% humidity, so I would say it works but needs to be treated as already saturated when you get it. It was a lot cheaper than other options I could find for Silica Gel, and readily available so I decided to give it a try.
I'm glad you said this because I can just get everything at store instead of waiting
Great, another worthy project to do, LOL. Thank you for clearly explaining and showing how to build a filament dry box correctly and completely!
You are so adorably German. I am greatly enjoying watching your videos. :)
@stephan from my experience, its good to check the contents of the little gel bags, if the crystal has shattered, its garbage, if its still a round pearl, its still good. you can also try to dry them out at routine intervals to ensure it stays dry
Thanks for the video. Appreciated your thoughtful to update link for non-indicating silica gel. A 2 year-old video is as good as new for a 3D printing beginner. Subbed.
Great tutorial indeed! The tip of using wood drill bits, alone, is worth enough for watching this video :-) ... Thank you for sharing !
This is exactly what I needed to see! I was thinking how to build a dry box. Now I know exactly how to do it. Thanks for showing us how. And thanks for being awesome! :)
now.... off to amazon to buy some stuff.
I agree.
He's got such a great way of explaining all the details and reasoning that it makes sense to even a noob to 3D printing like myself.
A+
This appears awesome! Can't hold out to appreciate similar to this. Great job.
Hello CNCKitchen, I was just recently recommended to check out your TH-cam channel, I’m glad I did, I’m brand new to 3D printing and you’ve got some excellent videos that I know will help me out a lot. Gotten tage from America.
Chances are you have a heat gun. Instead of drilling which might crack the container heat up the drill bit with the heat gun and just press into the plastic. Clean and easy
That’s a nice setup! I need to setup for my TPU..
Nice design and thorough explanation.
Thank you for your amazing work! To avoid having to open the box when switching filament, would a longer plug be able to hold a stub of filament and prevent backlash? Perhaps a few cm of hollow with small teeth toward the end might work? lol, pepper-shaped filament retainer plugs...
im about to do the same thing thanks Stephan! very nice tutorial:)
Branching out into printing with nylon, so THANK YOU for this.
I use a silamar setup but use extra large cereal boxes, works well.
Sebastian made a very true comment. Use Cabalt and DMF free silica gel, because some indicators are potentially toxic and carcinogenic! Replaced the link in the description with non-indicating silica gel. Health goes first! Just use the hygrometer to judge if the desiccant is saturated or not. I'd make sure that the moisture in the box is below 20%.
That link does not work for me
Kinda makes me glad I live in the southwest USA. Humidity doesn't often go above 40% unless it's monsoon season. (for an example, it's supposed to rain tomorrow, but humidity is only 20%)
With the rain here humidity can go up to 90% or sometimes higher, no wonder I haven't opened my CarbonX roll yet.
link for silica gel goes to "DRY&DRY unknown" :(
Just as an information: The general information about Cabalt and DMF is correct and you should look out for them, BUT the product in case (ST Trockenperlen) is Cobalt and DMF free (it's advertised as such and labeled by them as "nontoxic").
You just earned a new follower.
Love the video :)
Thanks Stefan! Simple and direct. I like it! ⭐🙂👍
Great idea 💡 👍🏾. Thanks for your content.
Another great video. Keep them coming!
You are fantastic! Thanks for the vids, they are all great!
Absolutely awesome!
Hi Stephan! First of all, I want to thank you for your videos, they are very clear and useful. My name is Federico and I live in Buenos Aires, Argentina. I'm about to put the box together to dry the filaments, but I have a question. I am using an MK8 and the box will be approximately 1.5mts from the printer. Will I have no traction problems at that distance? Thank you in advance and a big hug!
Great vid and lots of valuable info!
Yet another great video and fantastic idea. Even though I'm just starting out in 3d printing I'm going have to make myself one

Great and economical solution... Thanks.
I tried it but facing an issue of Under extrusion due to friction in tube. any suggestions ??
at work we use a vacuum pump to dry out materials during storage. We use mainly resins but i think it can work also with filament spools.
Marco Calenda i was just thinking of that. Does it deteriorate the material? In vacuum it starts to release gases which might be detrimental to the material properties.
@@konradritter7543 No. Filaments are stored in vacuum bags under negative pressure.
Vacuum pump? Seem a little overkill, don't you think?
Great idea i will definitely do that, thanks!
Your manner is so damn pleasant, Stefan. We could watch you for hours.
Great video Stefan :D
@CNC Kitchen you should make a video on how much silica is needed for a drybox like this.
He did say 1kg was plenty for his setup. The more you use, the less you'll have to regenerate it. Though I don't recall whether he said how often he needs to do that for his setup...
This is awesome.
Hello I really like your fillament test. Can I ask you to print 2 sets? First set do normally but the second one put in oven first. We are baking ABS injection molds at 80 C for hour witch really change its properties. It release stress from molding make it not to crack. I would like to know if it works on printed parts and different materials too.
I Know there is lot of stres in the material after print.
Amazing video. Thanks a lot.
I'm doing my first run of filament drying with your dry box - silicagel method. I'm still a bit curious when I have to change / refresh my gel. At which percentage do you normally change it. At the moment I have like 24°C and around 18% relative humidity. So it would be around 4g/m³ water..
Do you thing this condition is capable of getting some water out of my filament or do there have do be less relative humidity?
Thanks for sharing 😀👍
If you use the 45l plastic container from IKEA, you can fit two rows of filament. I can fit around 8-10.
can I use the gel contained in diapers or rice to replace the silica gel? Thank you for the teaching, Brazil's hugs.
When printing the box lid clips, I should probably not use the PLA filament that came with the Creality CR-10s? When attempting to clip the box lid to the box there is a slight cracking sound emitted. Would a different filament type be better for this application? Oh, and I applied the weather seal (on the list) onto the underside of the box lid. Maybe that is the problem? Cheers!
awesome as always! one thing to look into getting contained silica. much easier and neater. don't have rip the whole thing apart to empty, dry and refill the unit, and it's generally out free. I use EvaDry units. the have a heater and everything built in. turn color, pull the evaders unit, plug it in over night and then throw it right back into the box. Very handy that way with zero mess.
The Eva-Dry units use orange-to-green indicating silica gel, which contains methyl violet as the color-changing agent. Methyl violet is considered to be toxic, although it's unclear whether it's truly unsafe in this application.
yup, but it's deemed "potentially carcinogenic" in large volume, but safe enough and can possibly have medical uses. the Blue changing ones use cobalt chloride which is just plan toxic. In reality both are incapsulated in the silica and have very little chance of being harmful unless you over heat them and they pop open. which again, Makes the EvaDry safer as it's a much lower temp compared to an oven and is near impossible to have happen.
Probably not a problem unless it's disposed of improperly and kills some fish. ;( Do you find that one Eva-Dry unit per storage box is enough? How often do you need to "recharge" it?
ya, one is enough for each of my 72 qt boxes. Mid summer when here on New England shoreline the humidity averaged 80+ percent, it held under 30 percent humidity and I had to re charge over night like once a month. Winter, with heat on and super dry low 30% humidity like once every 3 months if that. That is going to depend on how often you open the box and such. I had 2 yr old filament that was soaked and was going to toss, thew it in there for a week or 2 and it was actually printable again, not going. to say it was perfect cuz it wasn't, but was usable for prototype printing where I just wanted to see how the shape is of the model.
Thanks. Sounds good. I'm going to give one a try.
Why do you store the filament in that orientation in the box? You loose space for potential more filament rolls for each box... I use the same IKEA box, Samla 22L, and I printed these, which you don't need to screw/bolt through the box (though it might be helpful to glue/silicon them in place) www.thingiverse.com/thing:1888463
There is also this version www.thingiverse.com/thing:1752874
And these clips remixed by me, from a great design I found on thingieverse also www.thingiverse.com/thing:2216335
so you only need 4 of them to close it properly. Requires about 16 cm build height.
The box has PTFE connectors on both the inside and outside, but I didn't have any PTFE tubes connected at the time I took the latest picture :)
Thanks for this well-thought upgrade :)
How do you keep the second filament roll from unspooling while the first roll is being used?
Thank you very much for the quick tips. :D
Now I know how to build my printerbox.
Danke für den Tipp. ;)
slt c est une excellente création pour protéger les filament .
What size bolts/nuts are needed for the tube brackets?
at what humidity level do you remove the silica gel from the box in order to dry it? 15% 20% ?
A little late here.. but, do the spools roll properly on the PVC without putting strain on the extruder causing under extrusion?
PLA is one of the "most" hygroscopic polymers. It is a nightmare to extrude in industrial extruders. I am sure you have gained some more knowledge since video though...definitely in fact 😄
Do you know of a source for tubing and Bowden connectors for 3mm filament?
Have you had issues with print issues due to drag? I made this box but when i was trying to print from it yesterday my prints were failing because there was too much drag on my spool. I have a Creality CR-10 v3.
Nice idea, did you not consider a heater like a commercially available dryer to assist the drying or do you consider that stage not required?
I'd be interested in the use of an active filament dryer also.
What kind of tube do you use for the filament? Is it larger so reduce friction? It doesn't need to be a ptfe
The silica gel for cats are working fine, but it's wet if you buy it.
I meant it makes zero sense for the manufacturer to dry it, it's just noch important for the cats toilet 😅 But when you dry it before, it's working great :)
Im using it since a year, dirt cheap and reusable 😄
Any reason for not rinsing the silica to clean, the ln obviously dry it in the oven before use?
I don't always buy silica gel beads, but when I do I use the affiliate link so my man Stefan gets rewarded for helping me build a dry box.
Can you stil use the oven to cook food after drying silica gel in it?
nice man
I love your videos!!!!! Freundlichen Grussen, Huib Schippers
Excellent
A good way to deal with 5kg spools as well.
Hi Stefan,
Thanks a lot for your works.
Is there a way to get all the components for the dry box in Europe?
All the links refer to Amazon USA.
Best regards.
In usa, use a sterilite gasket box. Ziploc also has a gasket box, but the sterilite is easier if your local home depot has them in stock. Note all 4 home depots in my area reported having between 1 and 7 gasket boxes online, but none actually did. Make sure to call ahead. It will save you a drive. Luckily the lady at the first home depot was nice enough to call ahead with the item code and saved me the remaining 3 drives.
Sorry, you are not in usa, you are in EU. Dyslexia sucks
Hallo, thanks for the tips and the good explained videos. 1 little question: where can i find the plug that you used to seal the box (min: 5:33)? It's the only part that i am missing to finish my Box. Danke im voraus
Just google for "Festo Blanking Plug" or just use a piece of PTFE tube and seal one end with hot glue.
I had the same question. Search for "pneumatic blanking plug" on eBay I like these ebay.us/vge1RV
teflon tube gets stuck in my connectors if I put it in. How to fix this??? do I take the metal things that latch to the connectors out?(this means looser fitting is this fine? Also what type of nuts are used for the p4-m10 things, I ordered m10 nuts they didn't fit idk what the threading is classified as(i managed to find 3D printed nuts though so that problem is not an issue)
5:05 Ahhh Smiagol
What type of screws and nuts do I need for that bracket ?
is it ok to just lay the filament on the silica gel? I want to keep my new petg filament dry and i can just put it on the spool if i need to use it
that box you linked to doesn't seem to be a Samla, but a "Lock & Lock" brand one that says it's only 22.9cm high, which feels a bit tight given many spools i have are around 20cm in diameter, did you actually try it with that box?
@
CNC Kitchen do you have a link to the bowden plug?
I had the same question. Search for "pneumatic blanking plug" on eBay I like these ebay.us/vge1RV
Can you link me to the nylon bag you use? I need to do a simple box for petg.
Super Idee - Halterung habe ich bereits gedruckt, ich frage mich aber, ob man die Rollen auch quer unterbringen kann, dann hätten mehr Rollen platz - notfalls müsste man hier mehrere Bowden-Anschlüsse unterbringen - was meinst du?
Klar, sollte kein Problem sein. Schau halt, dass der Biegeradius des Filaments nicht zu klein wird.
what about using rice instead of silica? have you tried it?
Hi everyone , i m using dry box like this but i havent any foam seal , Can i use silicone for same purpose ? İ cant get any lower level than %28 for now.
Does PLA and PETG need to be stored?
How to know if the silica gel is toxic?
Is putting them in an oven/microwave dangerous? Or what exactly is dangerous about using them?
I have orange silica gel that got blue, and I microwaved them to get rid of the moisture in them, I hope I'm not killing my self.
How could I do with direct driver extruder?
Can you share the stl (thingiverse) for the clips mentioned in 4:55 used to seal the SAMLA container
+darnokgazetapl Link should be in the description.
That's my implementation of the Thomas Sanladerer version. You find clips for the Ikea box in the links, too

Just found this old video. In more recent videos, it is mentioned that disccicant with indicators is bad for human health. But I have not yet found anyone stating why. Can someone please explain?
Dumb question from a newbie here. Seems like filament always comes in some kind of semi-airtight bag when you get it. When storing filament in a dry box like this, should it be kept in those bags or is it best to not use the bags to allow the silica gel to do its thing more readily?
Hallo Stephan, sehr gutes Video, bin gerade dabei mir auch zwei Boxen zu bauen. Kannst du bitte den link zu dem „Fitting plug“ teilen?
Weiter so 👍🏼
Dry your silica gel in Microwave oven 2 x 6 minutes and it is fresh as new.
Where does the fitting screw on? Is there a nut that goes on the inside of the box?
Was thiking the same lol, what did you end up doing to hold it ?
How does nylon hold up in moist environments after printed? Like making parts for kayak as an example.
It will get slightly softer due to the moisture uptake.
thanks
How did you connect the bowden tube to the extruder?
He didn't. It's not needed, as the filament is pulled through, not pushed like it is between motor and hotend in a bowden setup. The PTFE tube here is just used to reduce the exposure of the filament to moist air, and maybe to guide it if you fix the tube to somewhere. It also makes it harder for moist air to get into the box through the holes for the filament.
I'm planning on building something similar for my PLA, just because I'm storing it above my printer anyway, so I can just as well make it easily accessible when I want to change colors. For PLA I could probably get away with just making sure the hole where it leaves the box is tight (maybe with a sponge seal), but I think I'll add at least some tubing, maybe even enough to guide it close to the printer.
I love it when he says Guten Tag!
Kitty litter Silica Gel works very well, just dry it before in a oven or microwafe. Stefanie should have done that too, since it's much cheaper.
Thankyou its so much cheaper. The balls are around $55 a kg. Wile i can get 5kg of the cat litter for $17.
@@turtleman190 140Celsius for some time (hour or two) in a oven worked for me now. At some point it gets not lighter anymore - meaning it's dry.
@@calmarcalmar thankyou.
@@turtleman190 just saying: additionally I put them into the microwave now anyway at 350watt 10 minutes .. loosing again 2g per 100g silica. Now I have 5% relative humidity in the box, instead of 10%
@calmarcalmar thankyou. I will definitely be getting some because of my house plant's my apartment is extremely humid. I only just got a 3d printer. I'm going to print what i can in pla to start with, but I want to mostly use PETG. And tpu.
It's been two years since this video, have you had any humidity problems with your PLA now?
Always. PLA prints way more stringy when not properly dried.
@@CNCKitchen Ok thanks for the tip!
gut und Billig ;)
not relavent to the video, but i havent used my 3D printer in a while, so i never got to dry my silica beeds in a year. i got a new printer and didnt have a plave to put my drying box since the spool holder is on the top and not the side, so i had to take my filimet out of the box. being in California where the wether is crazy, the filliment did eventualy got wet, so i decided to go dry my silica bveeds finaly. let me tell you, those beeds took in so much moisture from the extream humidity caused by a summer heat wave. the heat was so bad that it rained hevily in the mountains and the evaporation from the rain reached my city. it felt like the sauna. in those few days, the beads turned to dark green. they look almost black. not sure how long it will take for them to turn orange again. but i think it will probably take more than an hour for me.
What is the blue gadget attached to the x-axis motor on the Prusa?
+Beerbatter That doesn't belong to the Prusa, it's the belt tightener of the CR-10.
Oh ok. Ha ha. It looked like it was part of the Prusa from the video angle. Thanks for the reply.
you can try to use the gels from beef jerky packs, plus its a challenge to get enough.. ;)
I've never heard of silica gel alongside beef jerky. They do, however, include an oxygen absorber to prevent rancidity.
You’re missing the link to the plugs for the connectors 5:35
Unfortunately the Silica link doesn't work again..
Thanks for the video :)
Thanks for letting me know! I think I fixed it.

Do I need to store fiberlogy fiberflex 40d like this???
it would probably be a good idea, but you don't need to. i just store mi rolls in some ikea zipper bags
Was under the impression that once your filament has picked up moisture the silica gel won't remove it, you need to put it in the oven. Is this not correct?
meucunt1 its correct you, if I have some old rolls of abs that bubble you stick it in the oven. And even with the setup you still will have to bake the nylon once in awhile
You can dry the Silica Gel/Desiccant in the microwave oven.
Hi Stefan!
Would also build my first Filament Dry Box. Would you share your special Bowden Coupler "protector"?
