Tetrahedron vertice
thingiverse
You can build a tetrahedron of any size you desire with four identical Morocan spiky stakes and 4 vertices. It is made up of cooking pick-stakes that are 3 mm in diameter. The interior diameter used in FreeCad is 3,6 mm, (r=1.8 mm), but on each printer you'll need to adjust it because they usually print a little tighter than intended.
