Pomodoro Timer Enclosure for ESP32-S3 Touch AMOLED 1.8 display

Pomodoro Timer Enclosure is a compact flip-to-start case for the Waveshare ESP32-S3 Touch AMOLED 1.8 display, built around a Pomodoro productivity workflow. Flip the cube face-down to start a 5 / 10 / 30 / 60 minute session, flip it back to pause. The device runs open-source Pomodoro firmware on the ESP32-S3, and this enclosure turns it into a sleek, self-contained desk timer.

It holds the complete device together with its factory black enclosure, so no extra fitting or disassembly is needed — the device simply drops into a snug pocket and stays put.

The model consists of a cube body and a front lid with a screen opening. The lid clicks on with four hidden cantilever hooks and an 8 mm deep frame, holding everything firmly while still coming off easily by hand thanks to matching scallops under the seam. A chamfered USB-C port on the front face keeps the cable accessible, and a light honeycomb behind the device lets the rear cavity print without supports.

Optional printed PWR/BOOT push-buttons let you power the device on and off without ever opening the case, and the four side texts can be engraved with your own presets. Four ready-to-print variants are included, each containing body, lid, and (where applicable) button parts:

Assembly takes seconds. The design is easy to print, works for desk use, and is a great gift.
