Foam wheel hub for n20 motors and combat robots
thingiverse
I designed the hub to fit snugly on a foam wheel by adding ridges. Printing with 10% infill will create a lightweight hub using 2-3 walls, or maybe 4 for added durability. This design should work well for typical 30mm, 40mm, 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 Decent motors for combat robots that work well with these hubs are available here: https://www.banggood.com/N20-DC12V-300RPM-Mini-Metal-Gear-Motor-Electric-Gear-Box-Motor-p-972972.html?p=T25030878732012108C
