Oktava MK-012 microphone blimp

thingiverse

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. <h2>additional parts</h2> <b>1) o-rings</b> 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. <b>2) fur / windjammer</b> 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. <h2>versions</h2> 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. <h2>license</h2> I´m releasing this as CC0 / public domain. Do whatever you want to do with it and have fun. I´d like to hear from your experience. And maybe you have some ideas to improve the design? Share it and let me know! =) <h2>more info</h2> The previous developement of this project can be read on https://jwsoundgroup.net/index.php?/topic/34162-3d-printed-blimp/ .
