 The four capsule holders come in two flavors, one for the upper two capsules and another for the bottom two capsules that connect into the microphone mount. The capsule holders have legs with fingers that interlock and hold the structure together. There are two styles of usable interconnections, horizontal legs (easier to print and assemble, a bit bigger) and vertical legs (more difficult to print and assemble but more compact).
