seesaw thing

just stl files, "hela" is just how it looks, do not print that. no pre-set printer settings, i used 5 lines in the walls, too much, 3 would be enough, and 3 bottom-top layers.

when asembling you need a barbeque stick to mount the seesaw arm to the piston, or something similar, holes in piston and seesaw arm are 3 mm.

mount piston inside cylinder on the seesaw arm.

then mount seesaw arm assembly on the base with the printed axle.

move cylinder as far back as possible, mark where it stops, move the cylinder as far forward as possible, mark it too, then glue the cylinder in the middle of the markings to alowe the piston and seesaw arm to slide in the seesaws elongated hole.
