HO scale 1:87 Cardanic transmission - customizible

Yet, another version of the cardanic transmission. I've included a SCAD model with 2 parameters:

1. Length between centers of spheres - default is 39 mm
2. Angle of rotation;

Now, you can adjust the length according to your needs.

The part "cardan_mini_axl.stl" has a 2 mm hole to fit on a motor axl or gear shaft.

The part "cardan_mini_motor.stl" is solid and fits into a 5 mm hole of a motor flywheel.
