I love my Gura Gear bag, but after many years of hard work, the handles started to fray and fall apart. Rather than getting rid of the bag, I designed some flexible TPU handle wrappers to go around the existing grips.
These are designed to be pretty generic and will fit onto any flat-style handle. It can be scaled in all dimensions.
The grip can be slipped over the existing grip and self-close. If you want to be on permanently, I would suggest using some flexible glue (ie shoe glue) in the overlapping area.
I have only added one to the print profile, so it is intended to print twice. This is to avoid stringing when printing TPU.
