I broke my buckles for my bags from Decathlon a few days ago.
I first wanted to design the same parts, which would be compatible with the original ones, and then I tried to upgrade them by adding more adherence and more resistance for 3D printed parts.
All of the parts are compatibles (original and new ones).
The buckle 2 is made of two parts, and the second has two version (an original one and an upgraded one).
I hope you will enjoy it.
The first part can be printed without support. Be careful about the support for the second one.
