4-sided die (paw-friendly)

thingiverse

The designers behind this die chose to stray from the standard angular design found in traditional 4-sided dice. This rounded die takes shape based on the unique intersection of a sphere and a tetrahedron, reducing the likelihood of injury when stepped on. Users can enjoy it with confidence. To replicate this custom design using PTC Creo 3.0, create a sphere measuring 22 mm in diameter and then intersect it with a tetrahedral shape. Once completed, proceed to drill holes and round off any sharp edges that may be present.
