Filament Sensor Microswitch box
thingiverse
Update: Feb 3, 2019 I inserted a spacer behind the microswitch for an even better fit with my current switch, and also expanded the filament tunnel to 4mm to accommodate Capricorn tubing inside it. This revised switch enclosure was inspired by bookmake's original design on Thingiverse. My microswitch looked identical but had a longer arm, so I tailored this case to match. I purchased my switches from Amazon at https://www.amazon.com/gp/product/B00MFRMFS6/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1. Edit: Revised it on Jan 8, 2018, to enhance switch operation consistency and allow for the wired switch removal and replacement without removing the filament. The photos remain unchanged, but the modifications are minor.
