the windscreen support mesh with four double helixes is not really printable in one go, the quality of the beams degrade as the structure gets taller - so split it into two sections (maybe we will need three) and move to six double helixes so that the slope of the beams is less and the print quality is better

h2n: wind screen support with three rings, add code for splitting the microphone stalk and capsule array mount from the bridge so that the capsule array can be separated from the the recorder body without making the whole system too big - includes threads for 8 pin mini-XLR connectors that couple the bridge to the stalk and array

h2n: major redesign, hide access to the top microphone mode selection dial as it is not really needed (the h2n needs to be in 4ch mode for the TinySpHEAR mod to work), with that disabled lower the bridge to touch the top of the h2n and hide the dial, use hull to get nicely smooth transitions, redo the columns to match - carefully match dimensions to the old column design as that was correctly hugging the h2n case, still need to test print the whole assembly so more tuning will probably happen soon

redo all the geometry for the triangular top connecting legs, make sure it works for tetrahedral microphone and octathingy, add code to enable leg rendering only when it is physically possible to create the connection (avoid capsule holders that touch each other, and for higher capsule angle avoid leg fingers that touch the adyacent capsule), for triangular connecting legs use the lef_thick parameter to define the height of the legs - otherwise for eight or more capsule designs the slant of the leg limits the minimum radius of the array

change design of bottom connector housing to use only the core metal part of the connector, much simpler and easier to attach using the two screws included with the connector (that would normally attach the internal strain relief); remove unnecessary external connector lock collar; redesign snap joint so that arm is stronger - this is still not optimal

add new capsule holder connection legs, horizontal with slanted top and dual fingers with support, interlocks much better than the previous version but only works for small microphone array radius (no error checking at this point), this is now the default; add bottom flare to microphone body that can house a 12 pin connector, includes a side collar that locks the connector in place; add click locks for snapping the top and bottom flares to the body of the microphone; modify the capsule array mount to include four holes for the individual capsule cables so that there is no connection to the resonant cavity below; change defaults for the mount so that the bottom two capsules snap more securely into the mount
