3D-printable linear actuator

thingiverse

This linear actuator is almost entirely 3D printed, except for the thread and some bolts, nuts, and bearings. Currently, it lacks position feedback or limited switches, which I plan to add in the future when integrating it into a project. It has a speed of about 25 mm/s on a 9V battery and draws approximately 1.7 Amps of current. The motor is rated for 36 Volts. Running the linear actuator on a 36 Volt battery will increase its speed. The transmission uses a belt-driven system, which features a GT2 timing belt and a 3D printed GT2 pulley. Although it may not be the most ideal transmission for this task, it will suffice for testing purposes. The linear actuator converts rotating motion into linear motion using an M8 thread. All parts (except for the 120 teeth pulley) were printed with a 1 mm nozzle due to the lack of high accuracy requirements and faster printing times. Some people are skeptical about using a 1mm nozzle, but I believe it's suitable for printing large objects like these without requiring precision. It works great for me.
