About this 3D model

This design is meant to sit above the printer, on the back wall. This allows the printer to sit close to a wall/take advantage of space. Other benefits inclue easier access to spool and no filament slipping. It requires bearings and rod. I used: (4) bearings (5/16"OD ; 1/4" ID ; 1/4" Width) (2) 7" lengths of 1/4" steel rod
