7-cilinder radial engine

Print the “Engine block” at 0.3mm, if printing lower make sure the bearing is not connected to itself (right click model/Split/To objects)

the “Finger Drive” can be used to hold the engine at a displaying angle (see second picture)

the counterweight works best if printed in 100% infill

for the orientation of the parts see the gcode.

everything else:

0.20mm

Lightning infill at 20%
