Flip-Flop (thongs) strap fix ring

I have been using Flip-flops (or thongs for my fellow Aussies) for the past 30 years and 90% of them end up going to the rubbish bin due to a faulty strap.This simple print holds the strap better from the bottom once it starts to slip off. Printed in PETG, if you need a smaller or larger size, just resize it through your slicer.
