Perfect Filament Guide

The filament on the Anycubic Mega S tends to get under quite some tension between the filament sensor and the extruder, especially when the printhead goes higher up. You can adjust the filament sensor to some sweet spot for a certain height, but at other heights it will not run smoothly.
So I decided to create the little *perfect filament guide*. A large wheel with a standard ball-bearing is tilted at the exact best angle to guide the filament always nicely up into the extruder. The holder clips neatly on the z-axis rack without need for screws.
