These are the kind of projects I would like to see the Printer manufacturer get behind. Possibly offer as an add-on and give a percentage of that profit to the community team who developed it. I'd buy the Sovol printer with tool changer kit, if I knew the Tool Changer Team was getting a slice! Love what you do!
Thank you so much for making this series. It's such a service to the 3D printing community. This man has spent so much time 3D printing, that his face has started 3D printing a mustache for charity. Incredible!
very nice! keep it coming....I'm super close to filling a shopping cart and following along your trail of crumbs to pimp my svo8. been here since 2017 and you've been one of (if not THE...) MOST helpful creator on the planet whilst I fumbled my way into 3d printing. I hope you get a raise
I'm addicted to these project videos. I've been eyeing the SV08 for months but was reluctant to buy it when my product development cycle wasn't imminent. I've bought 3D printers months before I needed them in the past only to have better options available in the interim. My ultimate printer would probably be an enclosed SV08 with four tool heads. Huge respect to everyone who is making the multi-head SV08 happen. Just as the SV08 was a win for Sovol and the community because they collaborated on open source development, I'd love for Sovol to make their own version of the multiple extruder SV08. The open source community and for profit companies are not enemies and should function as allies, as long as everyone follows the rules of the open source licensing agreement. Kudos to Sovol for the SV08 STEP files.
Excited about this build. I'm leaning towards getting one of these printers and wanted to do something similar. I would love to be able to be able to get up and running much more quickly thanks to all of your hard work. Thank you for sharing this journey.
This whole series is great, but for some reason this video in particular hit me how much work you are putting into this. Spool holder with build in filament sensor is a slick design.
Michael, Great job with this project and helping make tool changers more accessible to the masses! I always enjoyed and learned a lot from your honest and thorough videos. Thank you for the shoutout and looking forward to collaborate.
So to the back with the spools after all 😆 Most people have their printer ith the back against a wall. In my case, the printer stands in a shelf in a rack. Do you have to lift the spools of over the bracket? If so, this spool solution asks for lots of open air above the printer, and it will not suit my setup. But a different spool solution can always be made, even as an after thought, so in the end it works for all of us Very nice to see the progress! Thanks Michael 🙏
I had a similar problem with a long reverse Bowden tube sagging down into the print area on one of my 3D printers. I solved the problem by putting the PTFE tube inside polypropylene refrigerator water line from my local hardware store. The water line is rigid enough to keep the PTFE tube out of harm's way, but flexible enough to not restrict the toolhead's movement. It's also really cheap (at least in the US, it was about 4 USD for about 3m of material).
@@berlinberlin4246 The water line I used has about a 4.6 mm ID, according to my calipers (It was specified at 3/16"). A 4mm OD PTFE tube fits inside easily. The OD measures about 8mm.
Great job Michael, one suggestion when designing the back mounting one, is to make versions for enclosure and no enclosure. If someone puts an enclosure on their printer it doesn't look like that bracket will fit since your printer isnt gonna have the enclosure! Just a suggestion! Keep up the great work.
hmm, looks like you will come in close to half the price. I wonder how much time it will take in comparison (printing parts, assembly, tuning). The main reason people get Prusas is because so little tuning is required (since they have full teams dedicated to it). Super interested in seeing what the first prints will be like. I could also see a version of this where the filiment holder in flipped over like a rep box and feeds down into the machine. That way you could keep compatibility with advanced materials and not just be a PLA/TPU machine since you could then enclose. Lots of possibilities.
A metal zip tie from Bunnings will help keep your PTFE and wires tidy while parked. Printing up some small brackets to tie the 3 together like the Prusa XL will keep everyone neat, but plastic tip ties also work well!
Nice setup. This gave me some inspiration for deciding between Bowden or direct drive for my quad extruder setup that I’m building. I’m leaning more towards Bowden. Less weight, less design limitations. Thank you.
Thank you very much for your effort Michael. Can I ask what is a realistic timeline for this project to be faithfully released and when can we see your first multi material prints with it? I have an SV08 on which i would like to perform the entire process and get it to a reliable tool changer but i'm waiting for this to be tested/ready
Great build, cant wait to see everything working together. For the tangling issue, there was a video I watched recently where someone used 2.85mm Nylon Filament strains to support the tubes. Could be an easier and cheaper way to support this build. Just a thought from my side ;) Keep them videos coming. Loving it.
Another way to reduce the flop of the ptfe, is to add a glass fiber rod alongside it. It does need to be secured at either end, but works quite nicely. I used 2mm rod to keep my ~80cm cable loom in the air, and that is plenty stiff. I'd probably go down to 1, or maybe 1.5 mm for this.

FYI when tapping in a bearing you want to only hit the outer race. Hitting the inner race of the bearing bends and tweaks the bearing support rings. If it doesn't grind it can cause unnecessary pressure on the balls lessening the life. Try a socket that fits the outer ring race of the bearing.
The build is coming along nicely. When do you think some of the files will be released as I am working on my own and would be keen to get my hands on your PSU mount for the MeanWell and also the upgrade 2020 mount for the top docks
I hope part 6 of this excellent series arrives soon. I just bought an SV08, with quieter Noctua motherboard fan and MicroSwiss hot end upgrades. I have a product that I want to print on it that would use PLA as support material and PET-CF for the part, and it would be great to be able to print some TPU on both ends of the part for impact resistance without needing to print TPU end caps separately and assemble them. I'd love to be able to add one or two print heads to the SV08. Thanks to Michael as well as the DraftShift team for this awesome work.
that project is good reason to buy sv08, only problem is filament drying, with petg it will be really difficult. Another problem is how much space is necessary behind printer.
You might be able to take some of the floppyness out of the bowden tubes by have a short piece of solid tube over the ptfe tubing closest to where the filiment first enters it. Just a thought, may not work but I think it would be a shame to have to move it all to the rear of the printer.
Is the SV08 already working? It would be nice to see some b-roll with the printer actually printing, even if some things like multiple spools are not attached. But it would be nice to see some actual color changes, maybe with a small benchy or so.
The one big issue I can see with this is no moisture enclosure for the filament. To me the extra faff of extra drying seems like itd be quite a pain. That said, its really looking like it's coming along. Completely unrelated, have you seen TPU for AMS?
Loving following this series, and can't wait to hopefully follow on at home with my SV08 one day when it's done! A question- in the original video, you swap the power supply for a bigger one to power all 5 toolhead. Do you think the original might be sufficient for just two toolhead (one more than stock)?
Nice project! The question is ask myself is if the integrated power supply is not sufficient for only 2 toolheads? As they not really work mainly in parallel, more in a sequence? You would also not need the birds nest, as there are spare USB ports on the mainboard. Simply then go with a complete new cable from the mainboard to the toolhead 2. (D+, D-, GND, 24V). Then the cost for the 2 toolhead variant can be decreased a lot?
Love all your videos. Would you consider making a video on all these different build plate materials (PEP, PES, PEL, PEB......) ive been seeing lately. I cant seem to find any videos on what they are or best used for.
i think if you flip your spool rack 180 degrees and mount it to the front you can get away without having to redesign the printed parts ... im sure you will figure it out
i would keep the position and attach the pfte tubes to springsteel stiffening bands - why do compromises on the ease of use when you can engineer it to work? :)
I'm curious if those spool holders work well or if the spools tend to wander on the rollers. If they do it might make more sense to make them more convex and put flanges on the sides instead.
Love this series! Have you by chance got this up and running? I’ve found a few videos of builds, but have yet to see it running consistently. Would absolutely love to support and build out this mod for our SV08 that’s on the way.
Instead of moving your assembly to the back, is it possible to somehow move the electrical cords to the front so they can be coupled there? I really like your front mount spool solution and would hate to see it go away.
11:04 Where can I find the updated modular dock? I checked the modular dock github and it's total mess. Million folders, unclear instructions, etc. Assembly guide shows 3 bases, none of which is compatible with SV08 tool head, DragonBurner seems to be the closest to what you've shown us in last video. There is NO mention, which base is for what tool head. I really wish they stop updating the files for a moment and make clear and easy to follow step-by-step guide for us in a first place. The project seems very interesting, but the documentation is the main reason, why we don't see more SV08s with this tool changer style.
Doesn't the varying weight (filament being consumed) on top of the printer cause the resonance frequency to vary, and therefore the print quality to change over time? Or can the impact be ignored?
I was wondering how you gonna connect 5 filament sensors. I'm working on design where I would like to use 5 of those BTT SFS's but I don't have enough knowledge to connect it to my BTT Octopus Pro. And set it all up in klipper. Is it possible to run it in series?
It's a shame the XY gantry moves in the Z direction. If the SV08 was a coreXY printer with the XY stage at top and the build plate slowly descending under it, it would be possible to hang TPU reels above on bearing hub reel holders and not use any reverse Bowden tubes.
Hey! Nice work! Thank you very much! If you sell a package with all the things i need for a multihead conversion, i would pay you 25%-50% more than buying every part separate
The rollers, e.g. at 10:46 are concave. This is contradiction to the conventional wisdom of putting a crown (convex bulge) on pulleys. Do the filament-spools behave differently than belts? Do you see the spools crawling off to one side?
Can anyone show me the link on the toolchanger CAD project or to STL files? I have 2 SV08 toolheads as well as the SV08 itself, but I can't find the toolhead's part for a toolchanger
Is anyone working on a version that uses the enclosure? I have ideas for how I might try to adapt what I've seen so far, but no point in reinventing the wheel.
I have an enclosure and already ordered extruders and other stuff. Will start the transformation as soon as I see the first successful multi toolhead print. I'll drop the doors and also take my own preferences on some details. Where do you see huge differences the enclosure could make?

I don't know about you guys... but I just can't focus on anything in any of these videos... Michael's moustache is just too distracting.

Get some thin music wire and use tiewraps to attach it to the ptfe tubing. The music wire is flexible, and will support the tubing at it's max length.
Cool to see that Microswiss changed their logo...
I would highly recommend some grease when your tapping holes
You might be able to take some of the floppyness out of the bowden tubes by have a short piece of solid tube over the ptfe tubing closest to where the filiment first enters it. Just a thought, may not work but I think it would be a shame to have to move it all to the rear of the printer.
Are we going to have a Christmas present of finalised instructions and software package to make this all work? I'm stoked to get cracking on this 👍

Never printed bearing before but I guess I'll have to try it.
Or just roll a PLA tube on a PETG axle. Works thmooth and for a long time...
Seems like zip-tying a piece of piano wire or (bike) brake wire to the bowden tubes might help keep them from coiling.

Have you tried using piano wire to make it less floppy?
do those rollers work well? that shape seems like the opposite of train wheels which are self-centering. i think you need a convex roller not concave!
Doesn't the varying weight (filament being consumed) on top of the printer cause the resonance frequency to vary, and therefore the print quality to change over time? Or can the impact be ignored?
I was wondering how you gonna connect 5 filament sensors. I'm working on design where I would like to use 5 of those BTT SFS's but I don't have enough knowledge to connect it to my BTT Octopus Pro. And set it all up in klipper. Is it possible to run it in series?
For the btt filament senor is it a easy switch?
