Parametric shotgun microphone...Loosely based on the Shure VT98M design
Dean Hedin Nov 2023

The model is parametric so you are free to alter diameter, overall length, and "slot gap". Altering "slot gap" will change the thickness of the slots. The number of slots will be adjusted accordingly along the tube's length.

You can print this vertically on an FDM printer. To stabilize the model you can turn on the optional "supportfins" option. This will create four "rocket fins" to help support the model. These are designed to be easily removed in post processing.

The intent is to utilize a noise canceling electret condenser mic element like:
Digikey CMR-2747PB-A
Taidacent 9750 Electret Condenser Microphone (amazon)
or others

The mic element
