add one more point that is later not used to fit the spline so that the transition between the two frequency regions is smoother

fit the spline only for the high frequencies, for low frequencies keep the A2B coefficients untouched, make graphs of filters better

add maximum amount of boost to limit filter ends after fitting the spline, this still does not work out in low frequencies, perhaps we need to fit the spline only in the upper frequency range and just leave the A2B matrix alone in the low frequency range

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
