A little hello from Switzerland,
Here is my first cigar-box guitar created entirely pieces by pieces for laser cutting. My PIRATE'S GUITAR is an electro acoustic mini guitar with a special short scale of 488mm and can be mounted with 3 strings like a CIGAR-BOX GUITAR (tuned GDg) or with 4 strings like a UKULELE (tuned GCEA Low-G). She is playable acoustically but also amplified through a passive piezo pickup include under the bridge. The body and the neck are made of 61 pieces cut with a laser cutter in 2 peaces of 3mm and 5mm plywood. It also requires 4 classical guitar tuning pegs, a piezo mic capsule (already wired with an output jack socket), some screws, a fast wood glue and some nylon classical guitar strings. The graphics are burned by the laser during the cutting. For the mounting, it's like "Lego", every pieces clips with the other with some wood-glue, nothing to measure. Just look at the video...

We have not yet drafted "Instructables", but it's coming. In the meantime we have already organized 3 workshops where 30 people had mounted their own Pirate's Guitar, at the FABLAB-FRIBOURG, here in Switzerland.
I hope that will inspire you. Best regards. NOTsoNOISY Guillaume Reymond.
One of our workshops. Just 1 afternoon to build their own instruments.
