    One thought to reduce the number of magnets needed would be to make it such that the hose and tool side key in to each other more. Basically, make it so that the pieces hold together when tilted or slid, and only come apart when pulled perfectly straight. Then you can use fewer magnets, because the magnets aren’t holding the weight, the plastic is.

      Thx for the suggestion. The magnets are dirt cheap. 200 for 10 bucks, but if I had to pay "real" money for them, I'd probably just do a twist-lock

    Magnetic attraction is about 10x shear. Not sure what pry force would be. Simply extending an internal straight section (cylinder) so that there's mechanical support in the pry direction will solve the issue without using all the magnets.

    I think a guide lip on one of the sides would help quite a bit. With enough depth, it would prevent twisting or sliding laterally, so the only degree of freedom is straight back where the magnetic hold is strongest.

    SERIOUS HEADS UP on using the dust collection on your grinder. you send a hot piece of metal from something your grinding into your dust bag full of wood chips and you will have a big fire very quickly. It happens.

    • @suprspi
      @suprspi 8 หลายเดือนก่อน +6

      That was my first thought too. All my dust collection is separate from my grinding collection, which I send straight down into water buckets.
      Remember, a glowing piece doesn't need to stay glowing all the way to the dust bag/bin, only until it reaches a suitably dusty atmosphere that it can ignite.
      Probably it's not gonna light a fire, but I've seen too many dust fires/explosions living in a lumber town to take the chance with my shop.

    I had same problem designing exhaust port for my fiber laser enclosure. The magnets have plenty of pulling force in line with opposing magnets. The issue is that they don't offer enough magnetic force in shear direction. You can feel this effect by placing magnet on the flat vertical metal wall and try pulling away from the wall vs. sliding magnet along the metal wall. To counteract that, I added in ring lip on the mating surfaces of the clamps. This allowed to use fewer magnets so that you don't need to pull hard to take part apart while still maintaining positive retention on the exhaust port clamps.

    Great ideas. I'm not sure why so many people are commenting about how you could reduce the amount of magnets by altering the connection to lock mechanically fit together, magnets are extremely cheap & the ease & speed of just snapping them together (especially when they self align) is so much better than trying to slide or screw things together especially when dust etc is involved.

    There are different grades of neodymium magnets - typically N35 to N55, with the larger number being the stronger. Also the bigger the magnet, the more pull you get, so lots of options if you need more magnetic strength - bigger magnet and/or stronger magnet. They come in all shapes and sizes too - discs, squares, ones with countersunk holes, and even long cylinders. I have used square ones with a countersunk hole to affix to a 3D print with a threaded brass insert.

    For orienting magnets I have two small handles, printed in different color. Each having differently oriented magnet glued to it. I keep these "tools" in my magnets box and use them when pushing other magnets into my prints. Makes it easy to not mix orientation.

  • @highchiller
    @highchiller 9 หลายเดือนก่อน +1

    The issue is the tild in which it pulls off the hose. Your first design had 4 magnets and it was not falling out straight because the 4 magnet setup was strong enough. But the hose pulled it off at an angle (tilted it away) which only needed to break 2 magnets first and after that the other 2 which is obviously much easier. So your test of the strength is not really telling you much about the actual strength. Another solution (instead of 8 magnets) would be to design a slid so that it cannot be pulled off by an angle but only straight. This design might even increase safety in a workshop as it doesn allow to break off at an angle.

  • @larrybud
    @larrybud 9 หลายเดือนก่อน +1

    I've made duct collection adapters for a buddy without magnets, but I made them with TPU. Allows for some expansion and contraction when trying to fit in slightly different sized connectors.
    re: Clearance, I designed a test piece of various sized holes and peg along with text next to each one to indicate the size, in 0.5mm increments. As he said, on small holes, tolerance can be an issue. So now if I need a hole which is 3mm in diameter, I grab the test piece I made and measure which one is 3mm, (which might be the 3.5mm labeled hole, for example), then I set the diameter appropriately in the model.
    Also, pulling force isn't the same as shearing force, as you soon discovered.

      Yeah I'm surprised we didn't just go with a slip fit connection. It leads to a little fun dialing in tolerance/offset as well as taper to ensure they slide together satisfyingly and hold tight until you slide them apart.
      I went with these types of connections on various vacuum hoses over the years. No magnets required and less plastic needed, too. Builds great skills with tolerances as well as I said. Next time maybe FFF!

      ​@@FunctionalPrintFridayI think it would be great if you performed testing on the hold force with that magnet arrangement to determine the performance gain. It would make a nice followup video.
      Alternatively I think reducing the number of sets of magnets to 7 would provide enough strength but yield some cost savings. You couldn't then alternate their polarity if you did 7 though cause you'll be left with two beside each other and it may then affect the self alignment.

    • @alfredtrietsch215
      @alfredtrietsch215 9 หลายเดือนก่อน +2

      With alternating polarity, though the self alignment may need to bridge double the distance (max 45° instead of 22.5°), the alignment torque force will be double while resulting from the combination of repellence and attraction working together in the same direction. Of course you may need some more manual force to bring the pieces together in case you happen to approach with near maximal disalignment, when all the magnets repel, but this is an unstable equilibrium that will easily flip to the stable equilibrium of total alignment.

    • @sdoc3

    • @alexg9362
      @alexg9362 8 หลายเดือนก่อน

      As @sdoc3 aludes to alternating also has the advantage of not needing to worry about overall polarity during assembly. As long as you do the alternating properly it will go together, no chance you end up with a repelling coupler. This is probably a far greater advantage than any gains in hold strength.

    You can dramatically increase the strength of each magnet by mounting it in an iron (magnetic) cup which attracts to a facing piece of steel/iron (bolt, plates steel, etc.). This directs the magnetic flux to a smaller area and is even better than stacked magnets. Plus you don't have to align the collar correctly to have it stick.

    I believe you have to account for the sheering force primarily because of the angle the hose makes with the appliance you want to connect to. Imho you can overcome this by designing a better ( more contact surface) connectors between hose and appliance.

    I would design it so the magnets are inserted from the other side. You can leave about 2 or 3 layers worth of material on the interface side that the magnet sits behind. This way, you'll never have to worry about the magnets popping out, and it will still be very strong. You also won't have to worry about trying to get the fit/tolerances right as you can just drop them in and secure them glue. Also, it'll allow you to add more magnets easier.

    Also, if you had designed the slip-over pieces with a cutout slot on one side (or opposite sides), you might not have needed to design so many specifically individual parts. Yes, you might need a hose clamp if the fit is a little loose on some tools but it would save a lot of time (design & printing).
    (You also *_could_* have used a handsaw to make a cutout slot on the multi sander piece before forcing it on. It would have made installing it so much easier - and you can take it back off to put the magnets in.) 😁

    One option for the magnets - reverse the polarity in each lobe as you move around the hose. That way you cannot get it wrong, the ring will always align itself.

    I love neodidium magnets but i have a rule i use when desighning a project using them, and its simply double the amount you think you need its just belts braces, but im very intereseted in your doubling back to back approach as this would be great if it works out 👍

    Did you consider making the fitting for the belt sander (left side) into a 90 degree elbow. Then the flex hose has less strain pulling the fittings apart.

    I like the dedication to the idea but 16 magnets per fitting is insane.

    • @jayfavel4447
      @jayfavel4447 9 หลายเดือนก่อน

      Insane in what sense? If the number really matters that much, buy thicker magnets. Or is it the staggering cost of 16 magnets at $.06 per magnet?

    Cool project, but if you use that grinding wheel on metal then the magnets will def attract all the metal dust that's made.

  • @eminence55
    @eminence55 9 หลายเดือนก่อน

    Interested on how much metal filing build up on magnets. If its annoying or easy fix(air hose blast).

    • @FunctionalPrintFriday
      @FunctionalPrintFriday  9 หลายเดือนก่อน

      Haven't gotten any yet, but time will tell. To remove filings, try a damp paper towel and kind of just wipe/pinch them off. The air blast is always instantly satisfying, but it just moves the problem to someplace else for later.

    Very nice design, probably I'm gonna steal it from you , or at least get inspired from it ;-). One thing on your benchgrinder and stripsander, you'll probably use it for metalgrinding. In combination with wooddust, you have a combustable combination. You should get a metal sparkarrestor (fine metal screen) in between your dustcollection. This way you avoid a firehazard when grinding metal.

    Nice job. It may have been some work to get everything as you wanted, but the results were worth it. I'm designing a similar system for my own dust collection system using magnets also. Speaking of magnets, I gave up on buying the cheap ones from amazon or ebay. Quality was far too inconsistent. I get all my magnets from total element now. N52 for highest strength. Catch you on the next one!

      @@FunctionalPrintFriday Oh believe me, I know lol
      I've been an amazon addict since 2006 and even before back when it was still mail order lol
      It's just hard to beat the convenience and prices amazon offers. I have a hub nearby as well. Many times I place orders late in the evening and they're still here next day. Even for many of the things I know for a fact I can get cheaper from aliexpress I'll still grab from amazon to get them quicker.
      As for the magnets, I did the amazon dance too; many of those listed have no rating at all, or aren't even neodymium even though they say they are. A few posts on reddit led me to total element. Not the cheapest, but the quality is there and shipping has been quick for me.

    I use a shop vac with a cyclone dust separator and would love to print some of these magnetic duct collection couplings. Any chance you've made the host side coupling that would fit? The hose I use is 2.5" OD. Thanks for the cool and useful videos!

    Woodcraft just released their own MagFitt line for what you designed. I'm curious how much the cost difference is between making your own vs buying pre-made parts.

    • @FunctionalPrintFriday
      @FunctionalPrintFriday  9 หลายเดือนก่อน

      Parts cost was definitely cheap on this project. Even with all the remakes and wasted magnets that I can't re-use from the v1 and v2 designs, I'm still under half a roll of filament and about 5 bucks in magnets

    Is the combination of 3D printing and red-hot filings from a grinder a good combination?

    • @FunctionalPrintFriday
      @FunctionalPrintFriday  9 หลายเดือนก่อน

      It's a good point. I will say that there's no sparks entering from either the grinder or sander. Neither of these get used for heavy material removal (and neither are up to the task). The grinder gets used for sharpening lathe tool bits, and the sander gets used mostly for wood. It's not powerful enough to run the kind of aggressive belt you'd use for any kind of serious material removal on steel. I *would* like to build a "real" belt sander at some point, but I won't use this system for dust collection on it.

    @freddowns9708 8 หลายเดือนก่อน

    Awesome concept. As a woodwork teacher I am am always shuffling adaptors and commercial adaptors are expensive. $25 Aus per fitting. Had been thinking of designing and printing my own adapters but the magnet idea is sensational. It also means the adaptor stays with the machine. Going to start designing to tomorrow 😊. Is your design available anywhere for a school to use ?

  • @mikescholz6429

    I take all my magnets, use a compass and identify north, 😢and stick them to a piece of steel with all the north poles facing up, and then I mark them with a red sharpie.

  • @dougcox835
    @dougcox835 หลายเดือนก่อน

    When you mentioned the magnets being close to each other and maybe interfering with each other I though, why not alternate them? N S N S... So long as they alternate on both sides they will still mate and the fields help each other.

    For all of the whimsical marketing Gloop does they aren't kidding when they say don't huff it. If you read the rather long data sheet that comes with every bottle, that stuff is not a toy and should be used with safety equipment.

    What CAD software do you use? I’m in the research phase before buying my first 3D printer (leaning towards Bambu X1C) I want to design and print functional items for my personal applications as well as to use in my small manufacturing business) and after watching a good number of your videos, I think whatever you are using might work for my needs as long as it isn’t a subscription based product. It doesn’t need to be free, just not an ongoing cost. I’d rather buy once, and cry once!
