The OpenScad of https://www.thingiverse.com/thing:4534126 was helpful to design the basic part for my violin, however, I Felt it very thin, and slippery, hence, I created a custom mount, that can put the mic near bridge.
Also I had a thought to clip on the Rhode Wireless go on the Violin instead. I did couple of differnt attempts however, remember using the tripod Flash mout for it earlier, and modified https://www.prusaprinters.org/prints/40508-external-flash-tripod-mount/files to be mounted on top of the clip.
