This has a 3.2mm fingerboard to fit into a lego minifig hands. This was a request from my daughter, and I think I'll slice this in half to print as my reprap clone doesn't do overhangs or support material. They want it for the abominable "Lego Friends" figures they have, but since they don't have posable wrists its not going to work for them. Ukelele are small 4 string guitar type instruments that every school in Britain seems to be teaching the kids right now. Part of EurIng Andy Southern's New Year Resolution of a design a day. This botched jobby will do for 12th January 2015. Sorry I originally put "Lego Ukelele" for the title instead of "Lego Ukulele". I'll divvy this up in two different ways for tonight. Ok..... Divvied it into the Fret File and the Sound Box File. Glue together by dipping in Acetone for 4 seconds then assembling. These were then Acetone Vapour Bathed in my £9.97 filter coffee machine from PC World. ITS A LITTLE TOO LARGE FOR A UKULELE, so it looks more like a Bass Acoustic Guitar.
