3d Printable Linear Actuator 3D Print Model

---When you buy this you will have 3ds, f3d, obj, stl and step files of the actuator you see in the picture. I will help you with your additional file format needs.

Used PLA material for all the parts they are just fine you can use whatever you want.
The motor I used is 775 motor (100 watt). So the maximum axial load theoritically 250 Newton(~25 kg or ~ 56 lb). But if you use 775 motor which is one of 150 watt, this time axial load will theoritically 380 Newton (~38 kg or ~ 85 lb). Also I did a test for the maximum load capacity and then ended up 200-250 Newton, same as the calculated force. You can watch the video below.

The Piston stroke is 120 mm and piston speed about 30 mm/s. So 4 sec to required to full stroke.

There is a small gearbox in the system. It has a 6 gear ratio.
The threaded rod is 8 mm diameter (M8) and the shaft of second stage has a 6 mm diameter. Nuts also M8.

I used three 608zz ball bearings for support to threaded rod. If you make this project, The body does not need to be so strong.

So you can print with %20 infill and 0.2 mm layer height for stationary parts. You should print the gears with lower layer height (0.12 mm -0.16 mm). Infill for the gears its good % 50 or %100

Part list • 775 motor-100W (You should use 150 watt) • 3-position rocker switch • M8 threaded rod (l=220mm) • M6 shaft steel shaft • 608zz bearing --- x3 • M3x40 screw --- x4 • M3X15 screw --- x12 • M3 washers --- x16 • M3 nuts --- x16 • M4x10 --- x2 (for motor mounting) • External Retaining Ring (M8) x 2 • External Retaining Ring (M6) x 2 • Cotter pin (M2)
