Automated window blinds by jetpuf

I created this to automate my window blinds.
The MG995/996180 that the servo alone would travel was not enough so I created a gearbox. When printing flip the gearbox 90 so that the flat side with the two holes is on your build plate. see update below
This slides directly into the end of the window blinds and replaces the mechanism to rotate the blinds.
Jan-2021 - I have updated these again. The version of blinds that Home Depot is selling now require the 2021 geared servo blinds gearbox.
Important! I updated the gears with this latest version to both have 16 teeth and use a different and more powerful servo. DS3218 servos available from a number of sellers (amazon) have 270* of rotation and do not need a ratio provided by the gears... Now both gears are 16T and there is more than enough power and rotation for the blinds.
Feb-3-2017 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_Geareed_Servo_Blinds.stl works on my older blinds.
