Raspberry Pi 3B+ PoE Texas Prusa Mk3 Frame Mount

This is a remix of a great case that I had used for years on my Mk2. After having lots of wifi issues, I decided I'd like to run my printers over ethernet, and also decided I might as well use PoE, to eliminate yet another power cable. 

This case was remixed to:

• Fit the PoE Texas hat by adding height, adjusting mounting and clearance inside the case, etc.
• Not interfere with the X axis when it is to the leftmost position, and higher up on the axis.
• Add 2x LED holes in the bottom for the Pi LEDs. 
  • Otherwise can re-use existing case bottom if you already have it.

Hardware Needed:

• 4x M3x22 (min) M3x24(max) for the case
• 2x M3x8 (min) M3x12(max) for mounting to the frame
• SHORT USB-A to USB-B cable for connecting the Pi to the printer (This right-angle one works great)
• PoE Texas Hat
• Raspberry Pi 3B+
  • Don't be like me trying to troubleshoot a 3B (non plus) not working for PoE.

Build Tips:

• You may need to ream/file out the mounting holes on the Raspberry Pi and the PoE Hat, until an M3 screw easily slides through. I used a small triangular file that I carefully turned to ream out the holes.

• Print settings are whatever you prefer. I used Prusament PETG, .20 Height, 15% Infill, No supports.
   
• Use zipties or similar to ensure cables stay out of the way of the X Axis and Extruder
  • An X-Axis motor strain relief print may help ensure the motor wires stay out of the way.
