Looks amazing right off the bed. The axle is really durable so you can spin it all you want and it won't break (just be reasonable). For me, it spins really easily and doesn't jam up. Enjoy :)
I personally had problems with bed adhesion while printing the round segments that stand out on the axle so I added a version where you have to draw on supports (or maybe just enable auto-generated supports? I haven't tried). I also added the step-files, so feel free to just do whatever with it!
