Servo to Lego shaft adapter
thingiverse
I wanted to up my Lego game and combine my love for Legos and my love for radio control. This was created in the pursuit or a radio controlled car made of Legos, but soon became part of robotic arms and drawbots etc. The detail is pretty small since I needed it to match the spline of the HXT900 (SG90) 9g servos that I was using. I am sure this will fit other servo clones as well. I looked all over Thingiverse and could not find a way to couple a servo to a Lego gear, so I made this one. You will need a SG90, HTX900, or equivalent 9g servo and a LEGO shaft to use this.
