Different lengths to accommodate various bed thicknesses.

These are 3D-printable "hold-down" pins designed for laser cutters. They fit into the hexagonal holes of a honeycomb bed to secure lightweight materials (like wood, acrylic, or paper) flat against the surface, preventing warping and movement during cutting. Included Files

Some versions include different grip or head shapes to provide more surface contact without interfering with the laser head's path. Why use them?

Crucial for maintaining a consistent focus across the entire material surface.

Unlike magnets, plastic 3D-printed pins won't reflect the laser beam or cause a fire hazard if the laser accidentally passes over them.

The ZIP file typically contains STL files for different pin variations, such as: Regular length for common honeycomb beds.

Since you have the STL files, you can scale them slightly in your slicer (e.g., to 98% or 102%) to get a perfect friction fit for your specific honeycomb bed brand.
