100mm x 40mm Mecanum Wheel

pinshape

What you see in these 3D prints are my initial test parts and too short bolts, but they proved that the design works perfectly! Don't tighten the bolts & nuts! Leave the wheels a little loose to minimize friction on carpeting. Hard smooth floors probably don't matter about tightness. My test wheel works great on my desktop even though the spinners don't spin at all. There should be nice smooth washers between all plastic surfaces, so you'll need 48 washers for each wheel or 192 washers in total. Print two of each side panel and four dozen spinners - but don't glue them! Mate side panel 1 & 2 with side panel 1 & 2 as you run the M3 x 70mm bolts to get everything in proper place.
