A raspberry pi + screen mount on the Ender 3.

It attaches to the front of the 4040 extrusion using existing fasteners.

Required fasteners:
2x M5x8 - attaches mount to extrusion
4x M2.5x4 - attaches pi to mount

The example shown is using Raspberry Pi 3b + BTT PITFT50 V2.0 running Klipperscreen.

I printed it using 4 perimeters and 50% gyroid fill, but probably can be reduced to 3 perimeters and 20% fill.

Fusion360 + STEP file included for editing/remixing purposes.
