About this 3D model

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.
