Traditionally, ukuleles are designed with aged koa wood, and it normally takes many months to manually shape and form an instrument.
Matt was able to design a 3D model of a full sized 13.875″ (35cm) scale length ukulele in SolidWorks 2013 in about a week of his spare time. He has been tweaking it ever since.
The material Matt used for his ukulele isABSplus. The cost for one neck, body and set of tuning pegs was about $170 and it only took about a day and a half to print.
