twist the pcb's so that there is more space for the big electrolytic capacitor and all boards can be packed in a smaller space - but this one is too small, soldering both sides would be a pain

complete redesign of the body of the Octathingy, all eight phantom power interfaces are now arranged radially instead of in two groups of four, this makes the body symmetrical and less ugly but it is still very bulky as before - this will also make it easier to incorporate a windscreen mount

render a tetrahedral capsule array with all capsules having three standard horizontal legs, they all interlock much better than before and the geometry of the array is almost perfect without having to visually look at it while glueing the capsules together

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
