I designed a replacement bridge for violinists (in case the original bridge breaks). I tested it on my sister's violin (I am a cellist, so I just played it like I would a cello) and it actually had comparable sound quality. I designed the bridge such that it uses little filament and has the potential to vibrate more than a solid piece. I would encourage printing this in something durable (I used PETG) and with as many shells as possible and 100% infill. You'll need it. Also, I would encourage printing it on glass.
