The 3D models are almost completely parametric and are designed to be able to be printed on low cost widely available 3D printers (at CCRMA we use an Ultimaker 2 Extended Plus printer, using PLA material). The design is modular and tries to avoid using overhangs and support structures. That is why each microphone assembly is made of a number of independently printed capsule holders interconnected by legs that interlock and hold the structure together. The capsule holders and the mount are glued together to create a 3D structure that securely holds all microphone capsules. A mount that can be clipped into a standard microphone stand is part of the design.

## About building microphones
|

|
|
|
|
Successfully printing a microphone assembly is only the first step in a long and complicated process. This also includes finding and buying the required microphone capsules, assembling the electronics (requires precision skill with the soldering iron) and finally calibrating the multi-capsule microphone to get the best performance out of it (you will need at least a single driver sound source and a calibrated microphone).

-The 3D models currently include the TinySpHEAR, a four capsule first order Ambisonics microphone, the Octathingy, an eight capsule second order design by Eric Benjamin and Aaron Heller and preliminary designs for 12 and 20 capsule designs (the BigSpHEAR_12 and BigSpHEAR_20 models). The models will be expanded as testing proceeds. Contributions are welcome.
