Filament Sensor Microswitch box

Update: Feb 3, 2019
I added a spacer in back of the microswitch for a slightly better fit with the switch I'm using now, and also expanded the filament tunnel to 4mm to allow Capricorn tubing to be used inside it.

This is a modified version of the switch enclosure by bookmake
My microswitch looked the same but actually had a longer arm, so I modified this case to suit. My switches were bought from Amazon here

Edit: Changed it some Jan 8 2018 to make the switch operation more consistent, and allow for the wired switch to be removed and replaced without removing the filament. The photos weren't changed, but the difference is minor.
