I designed this general purpose gripper to replace the CNC'd ones on my Rubik's cube solving robot
Sturdy design (2X2 rods), strong enough to rotate the cube and more.
Simple to build: no washers, embedded servo horns and standoffs
The horns are designed for 25T servo's (Futaba/TowerPro/Orion/Savox/ProTekAce/Bluebird...)
I will release the two specific parts for Hitech servo's family (24T) if required

for this project, I used two TowerPro MG946R
