Consider to follow if you like what I do.
Just ask if you have an idea to a lego piece you want to be made.
Each cylinder has 7.6cc of volume. Compared to a Scarlett 6, its 1/22th scale.
A Lego® engine is 1/12th scale of this
Diameter of this is ~15L or ~120mm

Before assembly you may need to sand down down pistons/cylinders and bore the rods with 5mm bore. Lego engine parts are molded plastic, this is not, obviously.
Printing and assembly
This is what to need
2x plates, 1 of each or 2 of "1"
20x black Lego joints
7x 3L axles
1x 5L axles
The pistons has different measurements on each side. They will only fit one way.
The version in the video is made without RodR and O5R
V and Flat shape engines coming soon or in the future.
Resolution: 0.2, 3 perimeters, 3 bottom- and top layers
