movable model of a four-stroke engine

I wanted to design a four-stroke engine model on my own :)
All you need is a 3d printer and some adhesive.

If you want to you can use two or more cylinders in a series switching to create an in-line engine. The best example would be the engine of the Audi RS3.

The engine size is about 68,7 cm³ and it will take about 7:45 h to print one model (75mm/s).

You will have to print "welle.stl" twice and if you want to build a in-line engine you need "muffewelle.stl", too.
