electric skateboard pulley adapter - 37T to 45T

cults3d

This is a 37T to 45T adaptor for electric skateboard pulleys! designed for the Backfire cloudwheel pulleys, but it works on any 37T pulley A few considerations: The STL has 0.5mm clearance, at first it might feel quite stiff but after a bit of putting it on and pulling it off it should wear in. If you have a better printer and want one with a smaller clearance, or if you want one with a bigger clearance for a less snug fit, tell me in the comments! I'll be happy to upload the files. Make sure your elephant foot compensation is dialed in! you don't want it to not insert completely! I haven't tested it yet, but plan to put it in use as soon as possible. USE IT AT YOUR OWN RISK! it's PLA so it's gonna wear down faster than normal pulley material, it still shouldn't be a huge problem as it just takes a few hours to reprint and replace it. If you have better materials, feel free to test and tell us in the comments! if you want to try it, you have to print it slow, hot, with many perimeters and with an infill of ~65%, as it was tested to be stronger than 100%. you're gonna need bigger belts for this. I don't know exactly how big, if you know, tell me! It's gonna be harder to find the right belts with the new non-adjustable mounts, but a set of adjustable ones should be arriving to me :)
