Headless Gourd Shaped Ukulele

This Soprano size ukulele is a 3 piece design:

* Body
* Fretboard
* Bridge

It has no conventional headstock i.e. headless, in order to minimize overall length. Instead, the tuning pegs are located at the tail end.

It has a groove in the neck to accommodate a neck rod to stiffen it as most 3D printed plastic is too bendy under string tension.

Use something like this for the in-neck rod:

Also it is meant to be fitted with simple friction tuners like this:
