3D Chameleon Adapter For Monoprice MK3

This is a Bowden replacement connector for the Monoprice MK3 Printer and it's various clones. This adapter allows the switch to be mounted in place of the stock extruder motor, with the new motors mounted to the top left/right of the frame using existing mounting screw locations.

The stock extruder motor plugs directly into the switch, which is triggered at the maximum value of the X axis. On some machines, it was necessary to turn off software endstops (M211 S0) to allow the X axis to "collide" with the right side rail to trigger the switch.

Using the stock "3D Chameleon for the Ender 3" configuration for Cura should work without issues.

Is possible, print with PETG, 30% infill at .3mm layer height. ABS will work as well. Insert one PC4-M10 into the top and push the PTFE tube all the way through to come in contact with the top of the stock hot end.

It might be necessary to add spacers or washers to get the exact desired location as the metal frame is slightly different depending on the model and manufacturer.
