This is a simple and versatile belt clip that can be easily modified to fit your needs. It works with various straps, such as those on backpacks, as well as thicker belts for pants.
 

There are two versions available: one with a flat inner surface for a smooth fit and another with two small elevations on the inside for better grip.
 

The design supports belt heights of 35 mm and 40 mm and accommodates belt thicknesses ranging from 1 mm to 4 mm. The base width of the clip is 20 mm.
 

If you need a different size, you can adjust the width by scaling the Z-axis in your slicer. If you require a custom thickness or a size in between the existing options, you can resize the entire model without any issues—or just write me, and I’ll be happy to add it!
 

Be mindful when using this clip on delicate materials like leather, as it may cause wear over time. If you're concerned about potential damage, the flat surface version is the safer choice. Feel free to leave a comment if you need a specific size!
