Radial Engine, 7-Cylinder, Optional Parts Kit

cults3d

This kit is developed to add the Motor Drive Device for my following model as option.https://cults3d.com/en/3d-model/tool/radial-engine-7-cylinders-cutaway In this model, there are many places that generate unavoidable rotational drag, and if it is too large, driving by the motor may be difficult. But if engine is rotated by the knob lightly with your finger, it can be rotated by the motor. The biggest drag is generated by friction between the No.1 and No.5 cylinders and the piston. It is important to smooth the layer step on the inner diameter of the cylinder, and the sharp edge of the outer diameter of the piston and the layer step. In my case, I was able to somehow drive the motor without using grease. However, I cannot guarantee the motor drive for everyone, so please only challenge those who are confident. A.
