Foam wheel hub for n20 motors and combat robots
thingiverse
I added ridges to make the hub fit securely on the foam wheel. Print with 10% infill for a light weight hub using 2-3 walls, maybe 4 for durability. Should work for typical 30,40, and 45mm foam wheels like these: https://www.banggood.com/16mm-20mm-30mm-40mm-45mm-50mm-55mm-Sponge-Wheel-For-RC-Airplane-p-1116891.html?p=@T25030878732012108C Here are decent motors for combat robots and work well with these hubs: https://www.banggood.com/N20-DC12V-300RPM-Mini-Metal-Gear-Motor-Electric-Gear-Box-Motor-p-972972.html?p=@T25030878732012108C
