Proximity Sensor Holder for Lulzbot Taz - Auto Bed Leveling

Proximity sensor holder for Lulzbot Taz that mounts where the fan does. There is a 12mm version and a 16mm version. Which one you need depends on your sensor's diameter. You will need a capacitive proximity sensor if your bed is glass. You could also use a inductive proximity sensor if you have the new version of the PRINTinZ Printer Plate aka Ninja Plate. You'll have to connect the proximity sensor to the z-min endstop on the rambo board and make adjustments to your Marlin firmware. I recommend buying a sensor that will run off 5 volts. You can use a 24v sensor but you'll have to convert the voltage back to 5 volts on the signal wire otherwise you'll fry your Rambo board. There are a bunch of websites online that show you how to do this.

UPDATE: I enlarged the hole for the proximity sensor by .5mm. The old files worked but you had to screw the proximity sensor into the hole because it was a tight fit. The new files should fix this problem.

A lot of people are wondering which sensors to use so here are some that will work with just a glass bed:
