Seeed XIAO ESP32C3 tiny keychain case

A pocket-sized shell for the Seeed Studio XIAO ESP32C3, a 21 x 17.8 mm board with a USB-C port and a u.FL antenna connector. The case is 27 x 23 x 9 mm with 1.2 mm walls, an internal ledge that grips the board edges, a USB-C opening on the short end, a 2 mm hole aligned with the reset button and a small channel so the stock flexible antenna can route around the inside. A 5 mm keyring loop is printed on one corner and the lid snaps on with two tabs. Print the body opening-up and the lid flat.

Boards this small only survive in a bag if the case is tight to the millimetre, which is difficult with a generic download. In SpeakCAD you describe the board, preview the case free in the browser, add a slot for a battery connector or a LED window in the chat, and download the STL when it fits.
