Ender 3 Pro Filament Guide

I made this to fit some OpenBuilds parts I had on had left over from a CNC router build. It uses a V-slot bearing. On my pro it aligns perfectly.

Parts needed:
8mm ID, 16mm OD, 5 mm width Bearing - https://openbuildspartstore.com/ball-bearing-625-2rs-5x16x5/
5mm x 20mm Screw - https://openbuildspartstore.com/low-profile-screws-m5-10-pack/
5mm lock nut - https://openbuildspartstore.com/nylon-insert-hex-locknut-m5-10-pack/
Qty 2 - 5mm ID x 1mm thick shims - https://openbuildspartstore.com/mini-v-wheel-precision-shim/

The shims could be printed.

Holder V2 has a 4.5mm pass through hole to eliminate any fitment problems. V1 is 4mm.
