Towel Hook for Guitar Stand

I needed a place to throw my wipe down towel for my Banjo/Guitar stand so I made this little hook that clips on to the back of the stand. The diameter of my stand is 22.25mm… so scale accordingly if yours is different. 

Printed at .2 layer height, structural, in PETG but should work find in PLA. 

I had to print with a pretty wide 5mm brim as my first attempt at printing in PETG popped off at the end of the print.
