This linear actuator is almost completely 3D printed (except for the thread and some bolts, nuts and bearings).I curently don't have any position feedback or limited switches installed on it, I will add them in the feature when I'm going to integrate it in a projecct. It has a speed of about 25 mm/s on a 9V battery and draws about 1.7 Amps of curent. 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 wich uses a GT2 timing belt and a 3D printed GT2 pulley, This may not be the most ideal transmission for this task but it'll do for some testing. 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 nozle because there is no high accuracy required and it goes a lot faster. Some people are sceptic about using a 1mm nozzle but I think it's good for printing large objects like these without the need for accuracy. And it works great for me.

I'm a maker. I design and create my own projects and build them from scratch. My favorite tools are my 3D-printer and laser cutter. I own a 3D printer since 2014 and still use it almost every day. I like to design 3D models and sometimes also animate it. Besides 3D printing and modeling I also like aviation a lot. I fly RC drones, helicopters and planes.
