Arduino Uno R4 WiFi case with LED matrix window

A protective box for the Arduino Uno R4 WiFi that keeps the 12 x 8 LED matrix visible. The board is 68.6 x 53.3 mm and uses the classic Uno hole pattern, so the base carries four 3 mm standoffs at those positions and a 2 mm floor. The lid has a 30 x 22 mm window over the matrix, a slot for the USB-C connector, a hole for the barrel jack and long openings above both header rows so jumper wires still plug in. Walls are 2 mm, corners have a 3 mm radius, and the lid holds on with four M3 screws into printed bosses. The whole assembly prints flat in two parts with no supports. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.
Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer? We print this part and ship it to your door. See its priceUpdated

Open

Create a free account (no card) and open this ready-made model in SpeakCAD. It renders in your browser, on your phone or computer. It is not a fixed STL: every dimension stays editable.
2

Adjust

Change its numbers in the viewer for free, or ask the AI in the chat: wall thickness, hole size, the thing it clips onto. AI changes use 2 credits per request (1 for a quick edit, 3 for a redesign), paid with a plan from Maker at $7.99 a month.

Print

Download a watertight STL or 3MF free, with your numbers and hand edits, or G-code sliced for your printer at the same price. After an AI change the download is included in every plan (4 credits without one).

Example prompt

Design a two-part screw-lid case for an Arduino Uno R4 WiFi board 68.6 x 53.3 mm with standoffs on the standard Uno hole pattern, 2 mm walls, 3 mm corner radius, a 30 x 22 mm lid window over the LED matrix, USB-C and barrel jack cutouts, header slots and four M3 screw bosses.

This prompt comes with the ready-made model when you sign in, in case you want the AI to redesign it (3 credits a redesign); changing numbers in the viewer is free.

Fit notes

A generated case can be made exactly as tall as the shield stack you run, which a shared download cannot know. In SpeakCAD you describe the box, preview it in the browser, raise the walls or add a Qwiic cable exit in the chat, and download the STL.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.

Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.

No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
