At the moment, all Modular Fiddle files, including design files in STEP and F3D, assembly documentation, and bill of materials, can be found on the Modular Fiddle page. I'll be bringing that data here as time allows.
The best comparison of the Modular Fiddle to a traditional violin is this spliced video, below. The wooden instrument is a Chinese made acoustic worth about $2K. The red Modular Fiddle uses the generative bridge, while the green uses a 'regular' PLA printed bridge. The purple/green violin is the Hovalin from Hova Labs.
Here's the full video, where I play the whole song on each instrument and talk about stuff.
