D-BOT Extruder Backplate Mod

thingiverse

This is an updated design for the original D-Bot extruder backplate created by spauda1. The original design performed well for me, but I discovered that the gap between the extruder gear and the filament feed hole occasionally allowed the filament to leak out of the gap, resulting in a bird's nest. I redesigned the extruder and moved the entrance to the filament feed closer to the hob gear of the extruder. After using this modified part for several weeks, I've found that the problem has largely disappeared. The .step file is included.
