A compact two-piece enclosure for a physical book reading counter built around the Heltec Vision Master E213 V1.1 (ESP32 + 2.13" e-ink display). Press a button every time you finish a book and the count is saved permanently — even when the battery runs out.
The front panel has a cutout for the e-ink display and a hole for the tactile button. The back panel closes the case and holds the Li-Po battery in place.
Included files:
- Front Panel v7.stl
- Back Panel V5.stl
- STEP source files for both panels if you want to modify them
Print settings:
- No supports needed
- Any filament works (PLA, PETG, ABS)
- 0.2mm layer height recommended
- 15–20% infill is plenty
The electronics that fit inside:
- Heltec Vision Master E213 V1.1 (ESP32 + 2.13" e-ink display)
- Small Li-Po battery
- Tactile push button
