Rep 2 Filament Sliding Rotating Bearing Guide

A three part rotating, sliding bearing guide for any size filament roll. I designed this for our Makerbot Repicator 2, but I'm sure it could be used on other machines. The filament guide pivots on a bearing, the bearing mount slides on the bracket, and the bracket rotates to align with either the left or right filament roll.
For the bearing I used a McMaster Carr P/N 60355K503 bearing. The bearing presses in and requires leverage (ie: an arbor press, don't use a hammer). I mounted the assembly level with and 1.25" next to the factory sheet metal guide tube mounts (thru the plastic and into the sheet metal) using a #10 sheet metal screw, and predrilled with a 0.155" dia drill bit. The mounting location both penetrates the sheet metal for a good fastener anchor, and is close to but clears the factory guide tube mounts when the assembly rotates.
