Experimental stringed instrument.
You want to print this with at least 4 shells or it will warp like the dickens when you put tension on the strings.
Standard guitar tuning pegs are mounted on the head, and the head is epoxied to the body (see photo). Use the peg shims if your pegs are too short to hold the strings against the nut. You may also need to use a triangular file to make the string guides in the nut a bit deeper. Three strings from a regular guitar are used. There is room to mount a 1/4" jack for a piezo pickup.
An attempt was made to design a sitar-style bridge on this instrument. It doesn't really achieve the desired effect although sanding down the bridge to a smooth finish may help. This is playable but I will probably design a better one with separate neck and hollow body as well as a longer scale.
