Filament runout sensor for 2040 extrusion (AM8)

thingiverse

I took a popular snap fit Denos filament guide design, found at Thingiverse (https://www.thingiverse.com/thing:2710135), and combined it with the simple yet effective eussrh runout sensor design, also located on Thingiverse (https://www.thingiverse.com/thing:1698397). My goal was to create a runout sensor that could be easily attached to the top of my 2040 extrusion in my AM8 frame and removed whenever I wanted. To ensure accurate holes for the nuts and screws, I only used supports on the bottom part of the design. You will need three M2 screws and nuts (12 or 16mm should work) to complete this project. My designing skills are still developing, so I chose to start with proven designs, and these two worked well for me.
