add a parameter to the capsule module so that we can make the slot in the mount narrower for a tighter fit, test rig: first test prints of the parts, tweak tolerances so that all pieces fit together, I need to adjust the length of the stalk and the size of the adapter so that the stalk does not move and the skirt is longer so that it grabs better the mount cylinder - the concept works fine and the stop for 0 and 90 degrees works as intended

make the wall at the top of the conic section thicker so that the capsule holder ridges have a wider seat, we'll see how this prints as the sloped surfaces are tricky - even the existing conic section does not print very well and has to be refinished by hand

initial design of a printable test rig based on the microphone stand mount, it is all flat printable and includes a lever to rotate the capsule holder and a detente that stops rotation at 0 and 90 degrees (cleverly done, I think) - tolerances will have to be added after test prints
