Welcome to the StarkEffects.com Puzzle, Caltrops
This is an ancient weapon, but how would you put it into a modern CAD program in 3-D so you could have it manufactured?
Caltrops Puzzle
A caltrop can be formed with a sphere having 4 spikes protruding from it.
Every spike is exactly the same distance from every other spike.
What is the Angle Between Any Pair of Spikes?
