Here's another version of the Cardanic transmission, complete with a SCAD model featuring two adjustable parameters: Length Between Sphere Centers - default setting: 39 mm; Angle of Rotation. This way, you can tailor the length to your requirements. You'll find the part "cardan_mini_axl.stl" equipped with a 2mm hole designed to fit snugly onto a motor axle or gear shaft. Meanwhile, the "cardan_mini_motor.stl" component is solid and specifically crafted to fit into a 5mm hole on a motor flywheel.
