AB  - This paper in an update of the *SpHEAR (Spherical Harmonics Ear) project, created with the goal of using low cost 3D printers to fabricate Ambisonics microphones. The initial four-capsule prototypes reported in 2016 [1] have evolved into a family of full-featured high quality microphones that include the traditional tetrahedral design and a more advanced eight capsule microphone [2] that can capture second-order sound?elds. The project includes all mechanical 3D models and electrical designs, as well as all the procedures and software needed to calibrate the microphones for best performance. A fully-automated robotic arm measurement rig is also described. Everything in the project is shared through GPL [3]/CC [4] licenses, uses Free Software components, and is available on a public GIT repository (https://cm-gitlab.stanford.edu/ambisonics/SpHEAR/).
