Vented cases for Raspberry Pi 4B, Pi 5, and Pi Zero. Base with PCB standoffs, lid with a locating lip, four M2.5 heat-set inserts.

Open-face design — on purpose. Instead of port cutouts that go wrong every time a board revision moves a connector, two side walls are left open (the USB/Ethernet end and the HDMI/power side). Every connector clears, every revision fits, and it prints without supports. If you want closed walls, the source script has a one-line open_faces parameter.

Specs

Mounting pattern: 58 × 49mm (Pi 4B/5), 58 × 23mm (Zero), M2.54mm standoffs, 18–20mm headroom above the board (HAT clearance)2.4mm walls, slotted floor and lid ventingLid fixed by 4 × M2.5 heat-set inserts (screws and inserts not included)

Also fits: Pi 2B, 3B, 3B+ use the same pattern as the 4B case.

Not included: Arduino Uno and ESP32 devkits — their mounting patterns vary too much to ship a fixed case. The source script includes a custom_board() function: measure your board with calipers, pass the numbers, get a case.
