Free Arduino & Electronics Enclosure STL Files

Cases and mounts for Arduino, Raspberry Pi, and your maker projects

Every electronics project eventually needs a box. Arduino cases, Raspberry Pi enclosures, PCB mounts, battery holders, and controller boxes turn a breadboard tangle into a finished device, and the free model scene has a case for nearly every board.

This collection curates free electronics enclosure 3D models: Arduino and Pi cases, project boxes, DIN-rail mounts, battery holders, and cable-managed housings. Every file is free to download from the original creator's listing. Fit is everything here, so check the board revision each case was designed for before printing.

Print enclosures in PETG for heat tolerance near power components, or PLA for low-current projects. Leave ventilation slots open, and print a test corner first if you are unsure the ports will line up.
