Ender 3 Spool Filament Guide

Creality Ender 3 Spool Filament Guide for horizontally press fit into the top rail next to the spool. I installed the Filament Spool on the top metal rail because I have no space for side installation. And that causes the filaments to be tangled up as the print extruder head moves up the Z axis. I make this to fix this issue, to have a place to put my other caliper, to have a protective cap/guide for the Z axis rod, and a couple holes to hang things or temporarily put the filament thread in.

Spool Filament Guide should be printed with scaffold "support" box checked. After printing, I have to use a small flat head screw driver to remove all the scaffold plastics. Installation is simply press and slide the "Guide" horizontally into the top metal rail. Be careful and not let the Guide hits the Z axis rod. Filament can be feed into the hole or just carefully feed it sideway in. See the attached pictures for how I setup and use the Guide.
