I’ve been working on a DIY e-ink family calendar called Inkora, but one of my main goals was to make the physical build as simple as possible.

The enclosure is fully 3D printed and designed so the main components simply fit into their prepared positions and the case snaps together.

No screws, threaded inserts or glue are needed. There’s also no soldering — the device uses a LaskaKit ESPink/ESP32-S3 board, a 7.5" e-paper display and a battery connected with their existing connectors.

Once assembled, the firmware can be installed directly from a web browser, so no Arduino IDE or compiling is required either.

The calendar itself supports Google Calendar and Apple/iCloud (including multiple calendars from both), weather, holidays/name days, waste collection and currently runs for 3+ months per charge.

I’ve now released the enclosure files and build instructions on Printables:

I’d be interested in feedback on the enclosure design in particular — especially the snap-fit approach and anything you would change for easier printing or assembly.
