Automated window blinds

thingiverse

I designed this device to automate my window blinds. The 180 degrees that the servo alone would travel wasn't enough, so I created a gearbox. When printing, flip the gearbox 90 degrees so that the flat side with the two holes is on your build plate. This mechanism slides directly into the end of the window blinds and replaces the rod to rotate the blinds. I have updated a variation which should work for older blinds with the rotation rod centered down the length of the blind. It needs a bit more tweaking to work if you want to slide the mechanism to the middle of the blind, it should work well though on the end as a cartridge. Offset_Geared_Servo_Blinds.stl works on my newer blinds. Centered_Geared_Servo_Blinds.stl works on my older blinds. Please see my thread over at SmartThings. https://community.smartthings.com/t/release-esp8266-arduino-servo-controlled-smart-blinds/75998 Code for the Arduino/ESP8266 is here: https://github.com/jetpuf/SmartBlinds Print Settings Printer Brand: Wanhao Printer: Wanhao Duplicator i3 V2 Rafts: No Supports: Yes Resolution: 0.21 Infill: 20 Notes: I used enough layers to connect the servo screw holes to the outside of the case. I think 4 layers... or 1.6mm using a 0.4mm nozzle. Flip the gearbox 90 degrees so the flat side with two holes is on your build plate.
