Ukulele friction peg

I recently printed a ukulele made by chucktobuck: https://www.thingiverse.com/thing:1367923

I had trouble finding friction pegs where I live. I decided to try to make something of my own. This is still a work in progress but I think this has potential. The nut locks nicely on the bottom edge allowing you to tighten the bolt in order to adjust string tension. I'll keep working on it and testing this design. Keep in mind that this part is specifically designed for this one particular ukulele...so modifications would be necessary for other ukuleles, violins guitars, etc.
