This is the enclosure for smart window blinds I designed. They cost approx. $6 per window and work with both Alexa and Apple Homekit.
Unfortunately, I am unable to upload all necessary files here. If you are interested in this project check out this guide: https://blog.hirnschall.net/diy-smart-window-blinds/
It includes detailed instructions, schematics, arduino code and pictures.
Print without supports.
If the voltage regulator you are using has an LED make sure to use a dark filament or spray paint the finished print!
