I took the lazy approach to printing a mount for the proximity sensor. I searched for it instead of designing my own. I looked at a bunch of different designs and went with one that I liked. It also holds a 5015 fan and blows air on the filament that leaves the hotend..



Aside from being able to print while away from the printer this will complete the removal of all micro switches from my homemade printer. It has min and max optical end stops for y axis. optical min for x axis and now just a proximity sensor and aluminum bed for z axis. Tonight I wire the sensors in and begin trying to figure out how to set this up in marlin.
