Omni Wheel

thingiverse

This is a 3D printable OmniWheel with an outer diameter of 70 mm. It was designed in Inventor 2017, so feel free to download the project and modify it as you like - focus on the skeleton file for changing dimensions. To create one wheel, you'll need: * 2 pieces of WheelFrameV3.stl * 10 pieces of RollerV3.stl * 10 pieces of 14x1 mm silicone tube (cut to size for each roller) * 10 computer screws for holding the rods in place * A 1.2 mm welding rod for the roller shaft * 2 M3 hexagonal nuts for aligning the wheel frames Extra features include an M6 nut that fits in the center and a counter sink with three holes for further connections. Assembly begins by ensuring the frame's bottom part is flat, using sandpaper to smooth it out. Next, verify that the M3 hex nuts are securely fitted. Then, join the halves together, checking that they're properly aligned at a 90-degree angle. Once everything is in place, use superglue to hold them together. Next, resize the holes of the rollers with a 1.5 mm drill bit. Cut the welding rod to size and install the silicone tube on the outside of each roller. Trim the tube to its final length before installing it on the roller and cutting it to fit snugly around the edges.
