Lapulele - A headless ukulele
pinshape
This is my first attempt at a headless soprano ukulele, and here's how it sounds. Instructions: I've moved the tuning pegs down to the body to simplify things, and they work okay but have room for improvement. The tricky part is that there isn't a good way to adjust the action, so attaching the neck needs to be done with this in mind. This version requires gluing the body to the neck and neck support. First, glue the neck support to the body and let it dry. Before gluing the neck to the body, stick the saddle into the holes on the body but don't glue the saddle in place. Next, dry fit the neck and turn it upside down so the fretboard is facing down on a perfectly flat countertop with the nut (fret 0) hanging off the edge of the counter. Place something thin (about 2-3mm thick) under the 12th fret. The ukulele should now be supported in three spots; one end is the saddle, the other end is the first fret, and the middle is the 12th fret. This is roughly the position the neck will need to be glued. Hopefully, the action will turn out fine, but if not, you may be able to correct it by printing a new saddle. You can stretch or shrink the saddle on the Z-axis to raise or lower the strings. I'd never played a ukulele before or even tuned one, so it took me a little while to tune it the first time, but it eventually sounded like a ukulele. I printed all the parts in PLA with 20% infill, four shells, 0.25 layers, and no support. The only extra help was printing the tuning peg on a grid.
