Snap-lid enclosure for an Arduino Uno

A protective box for an Arduino Uno with openings for the USB-B port and barrel jack, and a lid that clicks on without screws. The Uno measures 68.6 x 53.3 mm with four irregular mounting holes; the base uses 3.2 mm posts at those points, 2 mm walls and 1 mm clearance. The lid has a 0.3 mm interference snap lip and an optional slot above the header rows so jumper wires can leave the box. Print both halves open side up.

SpeakCAD lets you decide what leaves the enclosure and where: a slot for a shield's headers, a hole for a sensor cable, or a window for the on-board LEDs. Describe it, preview it free in your browser, and tweak the snap tightness if your filament runs a little large.

Create a snap-fit enclosure for an Arduino Uno (68.6x53.3 mm). Base with 2 mm walls, 1 mm clearance, 25 mm height, 3.2 mm standoffs at the Uno hole pattern. Cut-outs for USB-B and 2.1 mm barrel jack. Lid with 0.3 mm snap lip and a 50x8 mm header slot.

Change any number to match what you measured. The AI keeps the rest of the design consistent, and small follow-up edits after a download are free.
