This linear actuator is almost completely 3D printed (except for the thread and some bolts, nuts and bearings). It currently doesn't have any position feedback or limited switches installed on it. It has a speed of about 25 mm/s on a 9V battery and draws about 1.7 Amps of current. The motor is rated for 36 Volts. Running the linear actuator on a 36 Volt battery will increase the speed of the actuator.
The transmission is a belt driven one which uses a GT2 timing belt and a 3D printed GT2 pulley. The linear actuator uses an M8 thread to convert the rotating motion into a linear motion.
All parts (except for the 120 teeth pulley) are printed with a 1 mm nozzle because there is no high accuracy required and it goes a lot faster.
