?

so for the past few months i've been taking a scale-calibrated microscope to a few k67 samples and after averaging out all of the runout, tolerances etc have come to the conclusion that the construction is insanely simple. every single measurement on this capsule (in its specification at least) is either a whole number or a simple fraction. the grid pattern is just a 22 by 22 grid of holes 2mm apart where the holes outside the center circle are not drilled. the blind holes are 3 2/3mm deep at the point exactly (about 3.4mm deep to the barrel). the through holes are 2/3rds of a mm wide, etc. it's funny that i started this project thinking that I'd get every measurement correct to the highest precision possible, because if anything every measurement on the backplate is aggressively rounded. The more backplates I inspected, the simpler the model got...

It's an exact anatomical copy of a real k67 with all measurements and placement of everything exactly the same. FR charts and whatnot will come soon. I was actually thinking of using POM, do you have any suggestions? I was thinking POM because it's really dimensionally stable and it doesn't have a plasticizer to dry out over time

It looks nice.? What are the specs, size, frequency response?? Also, what type of plastic is it?? I have seen enough plastics become brittle over just a few years.
