Very instructive. I rarely/never do much with Saab parts, but I do make telegraph keys. Specifically, 3D printed versions. Virtually all keys are metal, usually brass. Trying to get the same stiffness with plastic was a challenging for me. Essentially, the key is made of beams. The process can print a beam as a solid which is very wasteful of material. But it can also print just solid walls with "infill" patterns inside that are basically a less dense core. Intuitively, I understood some of that was going on, but I new there was more. This study provided a lot of the missing pieces for me.
If you're interested, here's a link to a photo album of the latest key. It's loosely patterned on a Russian WWII semi-automatic key.
Thanks for posting your studies. They are always interesting. I often learn a great deal from experiencing someone's thought processes even if I can't use the material directly.
