Ikea Window Blind Motor controller + Firmware

I have developed a motor controller for the IKEA Fridans Blind. But you can also control any other stepper motor with it. 

I found the motor bracket on Thingiverse (https://www.thingiverse.com/thing:4889111).

I designed a case that contains an ESP8266, a DC-DC SX1308 Step Up converter, a A4988 steppermotor driver, a hollow socket and a button. I used a reed contact and magnets as endstop.
My firmware controls the shutter safely and can be controlled via mqtt or the button.

Buttons: https://de.aliexpress.com/item/1005001629210748.html (Typ 2, DIP)

The STL files are already older, I hope it's a working version.
