News: As requested, I also created a parametric H-shaped strap slider with the profile preset to fit perfectly with this quick release buckle. You can simply click on the profile to use it as-is, or tweak the parameters to create an H buckle of any size or style. https://makerworld.com/it/models/2449476-parametric-strap-slider-h-buckle-webbing-adjuster#profileId-2689059

This quick-release buckle is designed specifically for 15 mm wide straps, making it ideal for lightweight backpacks, small bags, pouches, and DIY projects. The classic side-release mechanism allows for fast attachment and easy release with a simple press, just like standard backpack buckles.

The model is optimized for 3D printing, with clean geometry and tolerances designed to ensure reliable functionality.
