About this 3D model

This is a fully functional pneumatic linear stepper motor with three single-acting cylinders. It can lift many kilograms and due to its large dimensions and 6 mm teeth pitch, it should be easy to build and assemble. The motor uses six pneumatic tubes and is best operated with three 5/2-way valves. Let me know in the comments if you have any issues, and I'm glad to help you out. This motor has large tolerances and should be easy to print on any printer with any material. For the pictured motor, I used PLA filament, 0.15 mm resolution, 20% infill. Colors: Vertigo Galaxy + Gold Happens. For maximum strength and optimal airtightness, use 100% infill.
