Raspberry Pi 4 - Octoprint Computer Enclosure by Svid

Last crawled date: 3 years ago

A Raspberry Pi 4 enclosure design for 3D printers running on OctoPrint.
-On the front you can find the main ports like USB and WLAN, 2 slots for HDMI extension, 2 holes for LEDs (I desoldered them from the Pi and wired it to the front) and an optional bigger hole for ON-OFF pushbutton.
At the back, a connector mount for main, 2 optional holes for Banana plugs (I use it for powering WS2812B strips) and a hole for AC switch

On the top there are holes for 2 SUBD connectors (I use VGA connectors for the additional 3.5" TFT), holes for 2 additional power switches (Arduino, LEDs etc...)
-In the inside I use a 4010 ventillator. Mounted by 4x M4x30. The Pi is mounted by 4x M3x10 screws. I don't use the USB-C for powering the PI, instead I soldered wires to all the 5V and GND pins from below and powering it directly from there. (The PSU should give 5-5.5V and at least 3A)

The cover should be printed by using change filament option. White for start, then black, red and finally green.
WARNING! I use mains inside the enclosure. Never tinker under voltage! Protect yourself! After assembling it, NEVER power the equipment at once. Be sure that every (low) voltages are correct, there is no short circuit or metal particles left inside.
