Imagine, you buy a new bag, you are using it for two days, and one plastic piece breaks and renders it unusable. What a disaster! Wait a minute, just bought a 3D printer… It is an opportunity! :)

Designed with OpenScad, script included in the case someone want to play with it.

Better print it out of some more flexible material such as PETG or nylon. I printed it out of nylon, to make shure it won't brake again.
