I liked this model as it is similar in concept to my hubless wheel project so i printed it to see what i could learn from it.

It works pretty well after you rough it out by spinning it alot but it often can lock up due to having too much play so it isnt perfect yet.

Printed great though and its a really fun little thing. Kindof like a spinner ;) thanks for uploading.

UPDATE: locks up less and less the more you spin it :D although i have not tried this under a load.
