This is my version of the 8 bit violin. A lot of things have changed since I stubbornly wanted to do it my way.
One of those things is that I wanted those nice chequered press-fit sides. This adds a nice purfing-like trim (struggled to make it really press-fit actually). The top has a slight curve in it, to give it a little more volume and to move away slightly from the blocked look. All part are designed for 3mm (ply) wood. That makes for ~40 minutes cutting time on our Epilog mini 35 lasercutter. This edition is cut from a local light plywood, most likely made of poplar, but any 3mm ply would probably do. Light weight is a plus if you want more volume from your instrument. To make sure the bridge does no come through the top deck, I designed a bass bar too, to go under the G (lowest) foot of the bridge. A sound post is left as exercise for the maker.

I have no idea yet how to assemble this whole puzzle, but at least all the side parts are numbered. My suggestion would be:
1 glue neck side part(see small holes for lineup, push a small skewer etc in there)
2 assemble end piece (side 1 + 2 backings + 2 rings + 3mm nut and bolt.
glue in bass bar, take note it has a slight curve to pre-tension it.
4 add panels #1 and #13 to top and bottom panels. Make sure the neck fits tightly. to top and bottom!
continue adding pieces to the side. They are symmetrical, so you can swap the numbers to the inside if you like. Or add/engrave some decoration to the sides, 8 bit vines etc would be a very welcome addition. ;)

6) Profit!
7) find out I actually made some mistakes, so you need to cut again... :(
