Spool hole bearing holder (Fits Hatchbox PLA)

Print one for each side of the spool. 54.5mm diameter plus a lip. Fits great in Hatchbox PLA from Amazon. Uses standard 22mm bearings. Bearings will need to be tapped in with a hammer, but they stay in place then very well. I included the sketchup file if anyone wants to change the size.
