Kala Ukulele Strap

So I got this Kala Ukulele from my parents in law and an ukulele strap from my wife.
Unfortunately the hook on the strap is made for a wooden ukulele und mine is out of plastic. The soundhole is a little deeper than on an ordinary ukulele.

So I just "designed" another hook, tied it up the strap with a piece of fabric and *tada* it worked :D

Well it is not pretty but it will do the job. feel free to remix and to adjust so it fits your needs.

I printed it in PLA with 50% infill at 0.15mm but I'm shure different settings will work too.
