Press-fit pin construction toy

thingiverse

This press-fit pin measures 20mm in diameter and is designed for use at the Children's Museum of Pittsburgh's cardboard construction workshop. It functions similarly to Make-Do pins but lacks a locking mechanism. The grip surface relies on friction created by the natural grain of the material. To print, set your layer thickness to .32mm in PLA for optimal adhesion; be cautious with the first layer to prevent over-extrusion and slot fusion.
