Update 12.06.2025: design update for better lid snap and more guideline-compatible sensor slot
Small case that you can simply print (case and lid).
The case is made to store a:
- SCD40 or SCD41 board (no pin header, Aliexpress example)
- ESP32-C3 supermini (no pin header, Aliexpress example)
The lid and the case block in place the ESP32 and the SCD4x sensor.
My print settings are (for Prusa MK4S):
- 0.2 layer
- infill 10-15% (no big change in time and structure)
- no brim and no support
- rotate the lid by 180° after import
