Enclosure mounted filament switch

thingiverse

This is a mount for a micro switch that detects when you're running low on filament. It's designed for 1.75mm filament, but can be easily modified to fit 3mm filament. The mount attaches directly to an enclosure, which I use from Ikea. To help with modifications, I've included the SolidWorks and STEP files so you can tailor the part to your specific micro switch needs. All you need to do is connect the micro switch to your Octopi GPIO pins and utilize the Enclosure plugin to read the input and determine what action to take when filament levels are low. In my setup, I have mine configured to pause printing when it detects a lack of filament. You can access more information on this plugin at https://plugins.octoprint.org/plugins/enclosure/.
