Arduino Uno R3 Case 3D Models and STL Files

This collection gathers 3D models for housing an Arduino Uno R3, from plain boxes to shells with cutouts for a screen or a battery. Most files are drawn for FDM 3D printing and include a lid, a base or a breadboard insert. It gives you a way to compare enclosure styles before opening a model page. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Arduino Uno R3 Case 3D Models and STL Files»

The simplest entries are closed boxes with a lid and small openings for the USB and power connectors. Other designs add a slot for a half-size breadboard, a window for an OLED display, a holder for a battery pack or a hole for a reset button. A separate group is built around mounting: wall brackets, magnetic backs and flat bases that keep the board on a desk or a panel.

Before printing, read the model page for the board dimensions it was drawn around, since clone boards can differ slightly in hole spacing and port positions. Check how many parts the enclosure has and whether they join with screws, snap fits or glue, and whether the author lists supports, layer height, material and wall count. Photos of finished prints show how the openings line up with the connectors better than a render does.

If the results are too narrow, try other terms: enclosure, box, housing, mount, tray, or the board name plus the feature you need, such as breadboard, display or DIN rail. Related searches include cases for other Arduino boards, ESP32 and Raspberry Pi enclosures, and project boxes for electronics in general.

FAQ

Perguntas frequentes

Will a case for one Uno R3 board fit another?
Not always. Port cutouts and mounting holes can shift between manufacturers and board revisions, so compare the dimensions listed on the model page with your own board.
Do these enclosures need supports?
It depends on the design. Overhangs around openings and lids often print without them, while recessed ports or long bridges may need them; the author's notes usually say which.
What material works for an Arduino case?
PLA is common for indoor projects, while PETG or ABS are chosen when the case sits near heat or gets handled often. The model page usually names the material the author used.
Can I use a case with a breadboard insert for a permanent build?
Yes, but a breadboard takes up space that could hold a shield or wiring. If the board will stay assembled, a plain box with room for connectors may be easier to close.
