About this 3D model

This contains all of the base parts for the printrbot in one tiny tray. (Extruder, Gears & Clamps Sold Separately. ;) ) Full Tray Fits on a 7" x 6" Build Platform! 2 Smaller trays: Tray 1of2: 4.7" x 4.5" Tray 2of2: 4" x 4" I had some trouble squeezing down tray 1 any smaller... Anyone with smaller then a 5" build platform will need to build Tray #1 on their own... (Tray a #1 contains: 2 Base's, Bearing Guide & X Motor Mount)
