Oktava MK-012 microphone blimp by janikhampe

Last crawled date: 3 years, 4 months ago

This is a printable microphone blimp made for an Oktava MK-012 small diaphragm condenser microphone. It should fit most other microphones with a shaft diameter of 20mm like the Schoeps Colette Modular series.
By putting it inside a fur windjammer it creates a windless space around the microphone´s capsule enabling it to be used outdoors for location sound work.
additional parts
1) o-rings
Next to the printed piece itself two rubber o-rings with the following specs are needed:
outer diameter = 26mm
inner diameter = 20mm
thickness = 3mm
The get inserted into the printed grooves and act as a slip-free and rattle-free interface layer.
2) fur / windjammer
Also you will need some kind of windjammer. Mine are from Rycote. They make really nice ones although they are pricey: https://www.thomann.de/de/rycote_baby_ball_gag_windjammer.htm . Ideally your windjammer slows down winds while acoustically beeing transparent.
versions
I included two versions. One without any support structures and one including two single layer support structures which help on the precision of the o-ring grooves. Choosing the version with the minimal support structures you´ll have to remove these after printing. I do this in a few seconds using a deburring knife.
