About this 3D model

This part is intended for the MakerBot Replicator 2 machine. Used to mount PLA spools that use a 38mm Dia center hole on the back of the printer. I bought PLA from a third party supplier and the spool did not work with the MakerBot supplied mount. The MakerBot supplied mount is ~51mm in Dia but the PLA spools I bought have a smaller (38mm dia) center hole. So, I created this new mount based on the MakerBot version but using a smaller diameter shaft.
