A 3D printed ukelele, in one piece, in one go, put pegs and strings on it and it can be played. Just like that!
Yep, you read well, the boards are printed in one go, and trucks and wheels are also 3D printed, all is PLA. Each board weighs almost 2Kg and needed an extra large spool to be made.
This is my first self made big printer, it is a bit rough around the edges but I've printed with this one an incredible amount of parts and is tremendously reliable (if you know how to treat it). There are no plans, models or STLs of this one, I designed it on the fly modifying and reprinting things as needed, I'm not sure if even I could replicate it.
