A compact two-part enclosure designed for standard 40x60mm prototyping boards. Originally built for a garage door opener project, but the form factor works for any small protoboard build — ESP boards, relay modules, sensor hubs, NFC readers, you name it.

Features

• Snap-in protoboard mounting — no screws or standoffs needed to secure the board
• Ventilation slots on the body to help dissipate heat from regulators, relays, or anything that runs warm
• Internal height clears vertically-seated Dupont connectors, so you can keep your jumper wiring clean without having to lay headers flat
• Two-piece design: main body + lid for easy access during development and debugging

Print notes

• 0.2mm layer height works well; 0.16mm if you want crisper vent slots
• PLA or PETG both fine — PETG if your electronics run warm
• Designed and sliced in Bambu Studio (3MF included)

What you'll need to assemble

• One 40x60mm protoboard
• Your project's components

Print, snap the board in, drop the lid on, done.
