PiCase: Raspberry Pi 4B Case | with Fan mount | Octoprint

Summary

A case for the Raspberry Pi 4(B). The lid is designed to attach a 40mm 5V fan for proper cooling of the Pi - e.g. the Noctua NF-A4x20 5V 40x40x20mm or similar. The case has cutouts for all connection points of the Pi and can (optionally) be mounted on the 20x20 aluminium extrusions of your printer:

Make sure to check out my PiCam case and balljoint attachments if you want to use a camera: https://www.printables.com/de/model/349328-picam-camera-housing-arm-20x20mm-alu-profille-atta 

Printing

Just print like you usually would. No support needed, your printer should be able to bridge these overhangs easily.

optional if attaching to printer: For the attachment to the printers' aluminum profile you need to print two or four M3 T-Nuts: https://www.printables.com/de/model/243890-t-nut-m3-drop-in-rotating-v-slot 

Assembly

1. (optional printer attachment) Insert the T-Nuts into the 20x20mm extrusions. Use short M3 screws to attach the PiCase to them. If your screws have big heads make sure they don't push on the bottom of the Pi when the Pi is later inserted. Using two of the four holes should be plenty in this case. Make sure to leave some room to plug/unplud the micro sd card on the back.
2. Put the Pi into the case. Angle the Pi with the usb hubs first for easy insertion. 
3. Screw the Pi onto the case using two or four short M3 bolts (Two should be plenty!) Just screw the bolts into the plastic, they will make their own threads. Don't worry, you can reattach plenty of times using this method before wearing out the attachment points of the case.
4. Attach the 40mm fan to the lid.
5. Attach the fan to the 5V and ground pins of the Pi.
6. Pop the lid on. Just push it on, it should fit tightly and just stay on.
7. Attach the Pi to the printer, set octoprint up and happy printing! :)

Other tips

• I recomment just getting a Nut&Bolts set with different length M3 screws if you haven't already got one.
• The fan guard you see on the picture is the jet fan guard from the Hero Me project - it's free on Printables.
• I spent a ton of time (and 6 iterations) on the case design, you'd make my day if you post a make of it in case you print it :)
