A remix of my OpenSCAD Klipper Expander mount for use in the Ender 3 Pro to Switchwire conversion  by boubounokefalos. This adds a mounting wing that mounts on the underside of the Y-Axis 4040 extrusion adjacent to the power supply.

You'll need:

• 2x short M3 threaded inserts
• 2x M3x6mm bolts
• 1x Klipper Expander board (this model was based on the Fabreeko model)
• 2x M5x10mm bolts 
• 2x M5 T-nuts

You can find this model and the original OpenSCAD re-implementation on Github.
