Venetian blind Gears

Two gear sets for 50mm or 2 inch venetian blinds with square rod.
Blind_gear.stl is an under drive gear set. It will not move the blind the full 180 degrees.
Blind_gears_23x6 is a 1 to 1, 23mm gear set 6mm wide which will move the blind 180 degrees.
The gears center distance is ~20mm.

I glued the gear with the round hole to the servo.
The other gear has a square hole which fits 6.5mm square rod.

I used a standard size 180 degree 40x20mm hobby servo.
The servo mount can be found her
