Vacuum Engine

A running model engine that uses a household vacuum to run. Put the vacuum nozzle on the intake (rectangular hole on side of the engine, outside the valve). Then manually spin the flywheel clockwise until the engine starts. You will have to sand all the moving parts, mainly the piston and the valve. Also, put oil on the piston and valve to make it run a lot smoother. Simple cooking oil will work fine.

Print Settings:

-Tree supports on the piston and valve.
-All supports for the cylinder cover.
-"Touching Built Plate" supports for the cylinder.
DO NOT ROTATE any of the models, I have them exactly as needed.

0.2 layer height/resolution, or better.

10% infill for cylinder and cover,
50% infill for piston and valve. - This is important for strength

PLA - PLA+ should work fine
