MK3S Electronics Enclosure for SKR+Pi

Note: There is a newer modularized version that I would recommend checking out as it its more flexible than this version. But if you prefer this version anyway, feel free to use it.

This is a modified version of KalleKnall's Einsy/Pi Enclosure which I've enlarged to hold larger mainboards such as BTT's SKR line of mainboards or any other mainboard that has the same dimensions.

Bill of Materials:

• Parts from original
  • Printed parts
    • 2x small cablemount (for x-motor and heatbed wires)
    • 1x large cablemount (for extruder wires)
    • 1x bottom cover
  • Screws/Fasteners
• 8x M3 x D4.6mm x L5mm heat set inserts (other lengths should work too)
• Optional: 40x40mm fan to cool Raspberry Pi
• Optional: 30x30mm fan to cool stepper drivers
• Optional: 24V-to-5V buck converter to power Raspberry Pi
  • Banggood - This is the one I have
  • There are probably plenty of them in this form factor as it's probably just a clone of some design

I'm using heat-set inserts instead of the original hex nuts because I kept managing to accidentally get the hex nut stuck to the screw, and then would just turn in place, therefore being permanently stuck. Using heat-set inserts fixes this.

It also has some additional cutouts and mounting holes which are there for component's I've added to my setup. These includes a small fan cutout for a 30x30mm fan above where the stepper drivers should be located along the left side for added cooling (uses M3 screws), and a couple mounting holes located at the lower right which I used to mount a custom fan controller to allow me to use PWM fans (uses M2.5 screws) with Klipper.

I've left them rather than removing them as they shouldn't hurt by being there and if desired, maybe someone else can make use of them.
