Piston Keychain (press-fit version)

Another take on the piston-keychain with a movable connecting rod.

Designed to maximize quality at small size and reduce printing time.

Only two parts: cylinder head and connecting rod.

No glue/screws/pin required: the rod has to be pressed into the head until it clicks in place.

Force is required! I used a vice:

Tested with PETG, 0.2 layers, 0.4 nozzle, 2 perimeters, no infill required.
