Uses existing left side extruder to stepper casing for mounting, as right side screw will collide with the idler arm. I tried the original model and the right side will just break if you try to screw it tight. You will need to glue the cable guide. Print without supports, flat side facing down.
also included the version for right side mounting too, if you're keen on using it.
uses generic PC4-01 through pneumatic connectors. Thread is M10x6mm.
