UPDATED V4- https://www.thingiverse.com/thing:3494813

Building a wheelchair for a friends disabled guinea pig and needed wheels so this is a little side project ive been working on and this has turned out great. ONE PIECE PRINT!! I tried to optimize this for a 3d printer so its not your typical bearing :D After you separate the inner wheels and spin it for a few minutes it loosens up and keeps going without locking up even once :DDDDDDDD
