8" pneumatic wheel hub for FRC

thingiverse

This will work with AndyMark 8" pneumatic tires and likely most others too. The hub should fit any 200x50mm labeled tire. Print two of them, then assemble by using Six (6) #4-40x1" bolts that self tap into the plastic to keep the wheel together. For any use I recommend at least three more #10 bolts through the main bolt circle. Print Settings: Resolution: 0.2-0.3mm Infill: at least 25% Notes: Use this at your own risk! I have not printed it myself, so if it breaks, don't blame me. If you'd like a thicker more reinforced wheel, let me know and it won't take long to model. I recommend three or more shells with a substantial infill, regardless of ABS, PLA, or other materials. If you're comfortable printing at a 70 degree overhang, you shouldn't need support material. Probably best to use supports if you're unsure. How I Designed This: In full disclosure this is the AndyMark supplied CAD that I modified to be more printer friendly.
