A remix of a remix. I made some minor adjustments to allow for a Raspberry Pi 3 b+ to be used in this rack. I wanted to keep my case and the remix I adapted allowed me to keep my fans and case with only a minor change to the internal section of the model.
The author remixed this model.
The HDMI port on the Pi 3b+ hangs a few millimeters further out than anything on the Pi 4. I made some minor adjustments to the inside of the rack to allow for the HDMI port to clear the print until the Pi was seated at the rear of the print. This has allowed me to have my Pi cleanly mounted to my Ender 3V2 and still be able to use the heatsink case.
