About this 3D model

Designed this part because my straightened paper clip was too wobbly / loose. Now I can connect the servo and the servo saver with cotters / "splints". I use a 2 mm drill to drill the hole in the correct size.Cotters has a diameter of 1.6mm. A larger diameter near 2mm would be better. It is a part for the OpenRC F1 from barspin (Daniel Norée):https://www.myminifactory.com/object/openr-c-1-10-formula-1-car-16536
