Screwable case for Raspberry Pi + 3.5" Display + Fan // Klipper // Octoprint

thingiverse

This is a screwable case for a Raspberry Pi (1)B+, 2B, 3B, 3B+ and Banana Pi M2 Berry. It is designed for use with a waveshare-display (3.5inch RPi LCD B) and a Pi-Fan (30x30x7 mm) and has a pen-tray. I designed it around 3D-models of the raspberry and the waveshare-display and used normal printing-tolerances, so the final print fits very good. The rear supports of the raspberry-board are a little lower, as the display (only) comes with two spacers and so it rests on the screws. There are 4 M3-screws needed with around 15mm length. For the 5V connection of the fan, i exposed the pin on the display connector and soldered it directly. There is enough space in the housing for the transistor-circuit for fan-control, i placed the circuit next to the fan. There is also an extended version of the bottom, this is in my case for a pin-connector for an acceleration-sensor (where i exposed the 3.3V pin on the display and used free GPIOs for software-SPI, SPI1 cannot be used for ADXL345 and Klipper, SPI0 is used by the display).
