This is designed to hold a 28BYJ stepper motor in place to rotate the worm gear driver found in most household blinds.
There are other projects which mount a motor in a 2" track and drive the rod directly. My blinds are a 1" track and there's no way to cram a motor in it.
The mount fits into a 1" track and is adjustable along every axis that matters. It's assembled with some M3 bolts, nuts, and washers.
I've included a couple of motor adapters, but there are probably tons of varieties of these. The fusion360 design can be found on grabcad in case someone needs a different adapter.
I drive mine with an A4988 (28BYJ-48 motors converted to bipolar), and an ESP8266 running esphome.
The included gcode includes all parts of the "mounting arm" parts. You'll need to print the motor block and shaft adapter separately.
Print instructions
- PETG works best. PLA is too brittle. I used white eSun PETG.
- The motor plate and the arm it attaches to should be printed with supports for the rings. The slider tracks print fine w/ bridging.
