30deg Offset Filament Alarm & Guide
thingiverse
MendelMax2-inspired angled filament guide with standard mechanical endstop switch uses interference and two 1/4" metal crimps. Set an inch long plastic straw end (with a crimp loosely fit) in the top, so a roll of dust & debris catching cheesecloth will stay in place wiping the filament as it pulls thru. Extend straw into switch area and square out a hole for the switch paddle for 1.75 filament. The pin holes are not really needed. Hardware is M3 on the switch and M5 with washer on the rail face.
