Ender-2, ender-3, and CR-10 bearing filament guide

quick design i made after i noticed that filament was eating away at the extruder infeed!

you will need :-

a M3 bolt atleast 16mm long, and a nut.

a V623ZZ v-groved bearing 3x12x4mm or similar (https://nl.aliexpress.com/item/20Pcs-set-V623ZZ-V-Groove-Ball-Bearing-3x12x4mm-Carbon-Steel-V-Groove-Bearing-Used-In-Rail/32817763817.html?shortkey=eAbqYzU3&addresstype=600, these can be had for less then £3)

Edit 01/05/18 - added CR-10 file (untested atm as my cr-10 is mid job)
