RC servos are a common component in many robotics projects, but [Giovanni Leal] needed linear motion instead of the rotary actuation that servos normally offer. The 3D Printed Mini Linear ...

so it’s nice to know you can 3D-print linear gearing for standard micro RC servos and roll your own. Currently on revision 2, [Roger Rabbit]’s design is not just a quick and dirty solution.

Another common scenario for a typical servomotor system is incorporating it with another mechanism, such as a rack-and-pinion slide or a screw-drive, to achieve precise linear motion. The servo drive ...
