Description
I mixed the mount arm I liked with the case I liked for the Prusa MK3S and Raspberry Pi 4 to use with OctoPrint. I created a basic mesh case, one with a ribbon cable slot, a case for a 30mm fan, and a 30mm fan with ribbon cable slot.
With the fan version there is enough room to mount the fan inside the case, but not with heat sinks. I also cut out the grid around the fan header cables since they bumped up against the case. I was informed and had not tested it, but if you mount a fan on the outside, it will hit the motor on the X axis.
I used this fan: https://www.amazon.com/gp/product/B072FW3DDQ/
This is the cable I used to connect the Pi: https://www.amazon.com/gp/product/B00B5HS7TI/
I was asked about lowering the mount about 20mm to accommodate the Prusa light bar (https://www.prusaprinters.org/prints/3267-led-light-bar-prusa-i3-mk2mk3). I lowered the fan and ribbon cases to test and added a notch to run the light bar power wires behind the arm. Added images of the new lowered style to show how to attach the case with the Raspberry Pi dangling and to show how the light bar wires run. The new files are labeled "OctoPi_4_Top_Ribbon_Lowered.STL" and "OctoPi_4_30mm_Fan_Top_Ribbon_Lowered.STL".
