Retrofitted motor mount for blinds automation
Description
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](https://grabcad.com/library/1131522) in case someone needs a different adapter. I drive mine with an A4988 (28BYJ-48 motors converted to bipolar), and an ESP8266 running esphome. [Writeup available here](https://blog.christophermullins.com/2020/02/16/automating-blinds-with-a-retrofitted-external-motor/). Printing instructions: 1. PETG works best. PLA is too brittle. I used white eSun PETG. 2. The motor plate and the arm it attaches to should be printed with supports for the rings. The slider tracks print fine w/ bridging.
