Octoprint Case For Raspberry Pi 4B With QuinLED Dig-Uno

thingiverse

This is a Octoprint Case that is designed to fit a Raspberry Pi 4B. The body has pegs to hold the Raspberry Pi 4B without any screws needed. It also has slots for 2 buck converters (XL4015), a relay to control power to the printer, and slots for 2 QuinLED Dig-Uno boards. The lid has a cutout to mount a 30mm x 30mm fan. **I have also included a STL titled "Octoprint Case Body Without Dig-Uno" if you do not plan on using Dig-Uno boards and want to model that area to hold something else.
