REMIX Raspberry Pi 4B case for CR6 Max with 40mm Fan and Onboard Power and Converters by cghildreth

Last crawled date: 3 years ago

First, thanks to Olvin for the design and including an editable file for remixes. Following suit, I've included the f360 files for further remixing if desired.
I wanted an all-in-one solution for my CR6 Max to incorporate a Raspberry Pi 4b for octoprint with a quiet fan, included usb power for the Pi and a buck converter for 12v fan (which I had lying around).
The case is pretty self explanatory. You'll need:
2x M2.5 6mm long screws to mount the R Pi
2x M2.5 25mm long screws and 2x M2.5 20mm long screws to connect the fan cover to the electronics portion of the case (the 25mm long screws go through the R Pi mounting holes
4x M3 8mm long screws to mount the buck converter and LED voltmeter
3x M4 x 8mm long screws with t nuts to mount the case to the 4040 extrusion
LM2596 Buck converter for 12v power to the fan - make sure to adjust the power output before connecting the fan! (These: https://smile.amazon.com/gp/product/B07VVXF7YX/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 )
USB buck converter (make sure it can handle 24v incoming power) (These: https://smile.amazon.com/gp/product/B087RHWTJW/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 )
LED Voltmeter (These: https://smile.amazon.com/gp/product/B00YALV0NG/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 )
RPi 4b with Octoprint installed
A USB voltage disconnect (I used the one I designed here: https://www.thingiverse.com/thing:4762791 )
Wire to connect to the Meanwell Power supply. I used a standard LED lighting connector for power input to the case, and rigged up a wire to the PSU. I terminated the Pi side with a standard LED power connector and the supply side with terminals.
A jst connector set for the fan connection.
A right angle connector for the USB port and a short USB C Cable (This: https://smile.amazon.com/gp/product/B08P18HKYF/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 and this: https://smile.amazon.com/gp/product/B08D9SB161/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 )
A 40x10mm fan, preferably very quiet. I used a Noctua 40x10 that I had laying around.
Some basic soldering skills.
Refer to the pictures for how I wired everything. Undertake this project at your own risk. If you screw this up, you could fry your boards, cause a fire, electrocute yourself, etc.
I printed the files using my CR6 Max.
