I made these adapters so that the Zemismart roller blind motors designed for 37mm and 38mm roller blind tubes would fit the 44mm aluminium tubes (Acmeda type).
This allows me to use the much cheaper Zemismart motors available on AliExpress as an alternative for the Somfy Sonesse 30, which is the OEM blind motor system.
Printing
Print one of the motor adapter and two of the sleeve.
I used PETG, but PLA should be fine too. I increased walls for strength but otherwise it's a simple print.
Assembly
See photos - place one sleeve near the base of the motor and the other one over the provided idler assembly. Place the motor adapter on top of the existing mechanism. It is only slightly friction fit and might fall off into the tube - be careful when assembling!
I recommend assembling the motor end first and then placing the idler cap last.
Afterwards
This is up to you of course! I personally connected the motors to Home Assistant via Zigbee2MQTT and everything was automatically recognised. Home Assistant correctly sets these motors up as smart blinds and once I set the endstops, I can set the blinds to any level between fully open and fully closed.
