When making a Hadley telescope for my nephew, I ran into the problem of needing an easy way to adjust the screws to align the mirrors. While there are lots of designs for use with hex bolts, I did not find any that would utilize the knurling most socket cap head screws already have.
As such, I created a parameterized press-fit knob. The parameters are seen in the images, above, just undersize the head by about 0.015-0.010mm and you should get a good press fit. I also utilized a soldering iron to “heat-set” some of the knobs, though that was a far more tedious, and dangerous, endeavor.
Otherwise, I found these were great to make minor adjustments, instead of having to utilize an actual hex key.
Of course, they could be used in a myriad of other applications, as well.
