ball bearing wheel hub for lego

thingiverse

I was making a drift car and kept melting my cv joints so I tried the new hubs and found them to be geared down way too much. This led me to try to print my own hub, and for good measure, I added a skateboard bearing in the middle. Everything is press-fit, but some graphite lube or something similar will help decrease friction. You need a female cv joint piece to act as a substitute because a lego version will not work due to friction. The inner diameter for the skateboard bearing is 8mm and the outer is 22mm. I printed them with tree supports, and a brim with a little bit of glue on the bed. I can provide stp files on request but they are kinda messy lol
