Limit Switch Filament Run Out Sensor

I saw a bunch of limit switches cases out there, but none for the ones i had, so i designed one based around it.

The switch i have is close to maker bots version here

It worked on 2 out of 3 of my switches and the other one i had to bend the wheel around to get it to work so if you are having issues it might be that.

Also the filament is designed to only work one way, the cords should be hanging out the top, because thats where i have my pi mounted.

It requires PTFE bowden tube inserts in the top and bottom holes. I did this so you could use it with a bowden setup, and it seemed to help reduce drag on the filament.

in the end this works, decently, the switch presses on the filament a little much so it kinda binds a little, but otherwise its nice, if you can think of a way to help that go away let me know and ill try it

It would make my day to see people using these, so if you are using it, post pics!
