I made this microphone as a last-night solution to be able to amplify two violins relatively cheaply wireless at a friends wedding, so i designed it to use my AKG PT80 Transmitter that normaly uses a small condenser lavalier microphone with a MiniXLR connector.I made it to fit 1/1 Violins, will not fit smaller violins or larger violas without some adjusting of the modelI will add a picture of it fastened to a violin soon (forgot to take a picture)The clip is printed in Flex Polyester 45D from Plastic2Print and a correct alignment of the infill helps with getting it flexible in the right places (see image of how i used the infill at 20%), probably works great in NinjaFlex and similar softer materials with a more solid infill.The microphone capsule i used is a EC-0301/L bought at ELFA Distrelec (art.nr: 30-105-43) wich costs about 6.5€, chosen mostly because the impedance and the sensitivity is a good match for my AKG PT80 Wireless transmitters, and it was one of the most expensive so i thought that it might be good ;) but any condenser/electret microphone capsule with a diameter of 9.8mm and a length of <11mm works in the clip.
