A parametric belt holder to add eyelets in different strengths and sizes to a belt. I use the slim version for a litter bag dispenser and the strong version for a dog leash.

I printed mine in Extrudr Flex semisoft to give the dog leash holder extra tear strength, but PLA or PETG should be fine as well.

The provided OpenSCAD file allows full customization:

• belt dimensions
• width
• eyelet diameter
• wall strength
• eyelet position

The provided stl and presliced gcode files provide the following dimensions:

slim:

• belt dimensions: 41 mm x 4 mm
• width: 5 mm
• eyelet diameter: 10 mm
• wall strength: 3 mm
• hole position: centered

strong:

• belt dimensions: 41 mm x 4 mm
• width: 10 mm
• eyelet diameter: 10 mm
• wall strength: 5 mm
• hole position: centered

The gcode is mainly provided for the time estimate, I highly suggest you customize and slice the file specifically for your own printer.
