What it does

  • Sized to fit your exact strap width, no more settling for close enough
  • Perfect for bags, straps, and DIY gear projects
  • Simple, functional design that gets the job done
  • Includes beveled version for a smoother finish

Ever need a buckle for a cloth strap but couldn't find one in the right size? This parametric buckle is one of those useful 3D prints that solves a real problem. Designed in OpenSCAD, it's adjustable to fit your exact strap dimensions, no hunting through bins of hardware.

It's straightforward and functional. Not claiming to be the strongest buckle ever made, but it works for everyday projects like bag straps, organizers, and DIY gear. Whether you're wrangling tool organization or just need to wrangle a loose strap, this little helper has your back.

We include both the original version and a beveled variant that was refined in Blender for a cleaner look. Print it, snap it on, and get back to making cool stuff.

What it is made of

Designs like this print well in PLA. Compare the materials.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
