Spool holder/adapter for 8mm smooth rod or M8 threaded rod

A spool adapter for my prusa i3 wooden frame. Printed mine in PLA with 20% infill and .2 layer height.

The diameter of the inside of my spool is 39mm and the part does have a flange for both the bearing and the spool. The two bearings used are 608ZZ ones.

Since i did not want the bearing to come loose the hole is snug, I actually had to stand on the part to get the bearing in.

Print time for my printer was about 20 minutes, and mine is not very fast.
