Filament Sensor Mount for Direct Drive Ender 3 (Pro / v2)

thingiverse

I needed a filament sensor guide that works with a direct drive to go with my cheap Amazon filament sensor. Use a zip tie to secure the filament sensor to the mount. I designed it with a zip tie vs using the holes because it seems that many of the filament sensor switches have the holes in slightly different places, and also to avoid needing screws. The zip tie design makes it more universal. No supports needed. You may need to use a brim since the bed contact is thin in places. A well tuned printer can print this without a brim.
