This is yet another filament sensor. I made this to fit a microswitch I had. Everything prints without supports. It is not perfect, as it does not allow my printer to go all the way to the top. The cables coming out of the X carrier can touch the base. Feel free to improve it.
This sensor works with any of the available OctoPrint's plugins.
3mf file included.
