The file 'Window Opener / Linear Actuator 3D Printer Model' is (stl) file type, size is 260.6KB.
This was designed to be used as a window opener for me. But it can serve in general as a linear actuator.
Parts needed :
1x 10mm M4 thread sphere
2x 6mm 200mm linear shaft
1x 17HS3401 300mm lead screw stepper motor
2x LM6UU
1x 3x6x5mm patch SMD DIP button
1x DC female plug 5,5x2,1mm
2x M3 8mm
2x M3 10mm
2x M3 18mm
2x M3 5mm
6x M3 nut
You also need the flat version from this lead screw nut:
1x T8 lead screw nut (flat version/2-holes)
or
1x https://www.thingiverse.com/thing:4815442
The thread of the stepper motor and the linear shafts needs to be trimmed.
