MK7 Filament Guide for John Watson's Aluminum Extruder Upgrade

thingiverse

I bought John Watson's Aluminum Extruder Upgrade, hoping to resolve my extrusion issues. The upgrade was simple and useful, but skipped steps persisted. Upon closer inspection, I noticed the filament getting pulled off the drive gear by unknown force. Other mods didn't reveal this issue due to their complexity. To remedy it, I created a compatible filament guide for the aluminum extruder mod. After installation, no more skipped steps! I have only tested the guide on my Replicator 1 Dual (MK7 extruders), and it may not fit MK8+ extruders. Print guides using ABS preferred, but PLA works too. Set layer height to 0.2mm, fill at 15%, and extra perimeters to 1. Follow these steps: print the guides, place them on extruder assembly (loose fit), re-assemble fans, and screw everything back together. Finally, reload filament and enjoy printing!
