Raspberry Pi 4 case with optional 30x30mm or 40x40mm fan mount. No screws needed to assemble.

Print with PETG or ABS because parts of the circuit can reach as high as 80°C. I suggest adding support manually for easier removal, see preview.

Note, if the case won't fit the board, check out the audio jack hole, which has a thin bridge above and tends to hang below. You can ease the top part with a carver blade. See the photo with the red arrow!
