Ukulele String Turn Around, based on Norwegian Creations / Anders Strand's work

I wanted to design a ukulele string turn around and rather than completely reinvent the wheel, I downloaded Anders Strand's work from his site Norwegian Creations (https://www.norwegiancreations.com/2017/08/making-a-home-made-travel-ukulele/) and modeled mine on his work.  (Anders, thanks for sharing your work!)

My design is little more than a 16mm diameter, 50mm long cylinder with a 5mm bore, some ridges for strings, and a flattened side to make it easier to print.

I've also uploaded Anders' own work here - I hope he doesn't mind.  (It was published CC-4.0 SA, I think we're cool).
