What are the measurements of the stud the knob mounts to? Knob dimensions? Looking to get drawings to use this in a CAD model.

I measured mine and here's what I got: It's a split shaft with splines to help grip the smooth/soft ID of the knob. The OD of the splines and base of the shaft measures 0.227" and the diameter at the spline root measures 0.212". The split in the shaft measures 0.043" wide. The total length of the shaft is 0.388" from where it protrudes out of the threaded mount, to the tip. The split in the shaft and the splines are both 0.335" long. I'm eyeballing about a 0.025" x 45 degree chamfer on the tip. Splines are spaced 20 degrees apart; there would be 18 total, but two are missing due to the split in the shaft. I lost the knob, sorry.
