Geeetech Improved MK8 Filament Guide

A remix from thegman fllament guide. I extended some cylinder by 2mm, made some slope around the hole opening that resides near the bearing and extruder gear.

This is to help the filament go in much easier without being stuck on the heat break. Even the original design, would have the filament stuck at heat break upper end.

So far this design doesn't have any issues
