I designed this Ukulele after printing a few of the other Ukes on Thingiverse that were good but still had room for improvement.
Improvements include:
No buzzing
No sharp corners
Doesn't get out of tune on the higher frets.
2 halves fit together properly
machines fit great.

The 2 parts fit together snugly for me there was no need for glue but depending on your printer/slicer you may need to.
You will need 4 Uke machine heads just google B00EQ29KNG and you'll find the ones I used. I bought some machine heads that were too long so I made a spacer block you can add to the back so everything will still work properly.
also you will need 4 Ukelele strings.
You will need a print area at least 10.5" tall.
If you want to print this on a smaller printer let me know what size you have and I can try to split it up for you so you can glue the parts together.
I've improved everything I could think of but if you feel like there is something that could be better please let me know!
All feedback is welcome.

02/21/2015 - Added new files with neck and body cut in half for a smaller height requirement (now 5.35" or 136 mm tall) I haven't tried gluing these halves together so let me know how that works for you.

02/28/2015 - Added a spacer that you can add to the back of the head if your tuners are too long.
