This round theme is tiny and mighty — these beads are all around math solids! 

In this collection you will find:

All Five Platonic Solids:

• Tetrahedron
• Cube
• Octahedron
• Dodecahedron
• Icosahedron

And some of their Archimedian Solid “counterparts”:

• Truncated tetrahedron
• Truncated cube
• Truncated octahedron
• Truncated dodecahedron
• Truncated icosahedron
• Cuboctahedron

And, a little more exotic: 

• Reuleaux tetrahedron - it ist difficult to print!

Obviously, the list of the interesting mathematical solids does not end here. There are way more. Some where left out due to their closeness to a sphere - these are no easy print. Others due to the lack of my knowledge of them - let me know in the comments if there is an interesting solid missing.

Printing:

• All with a 7mm hole. You can change these in the 3mf file.
• Depending on your printer/Slicer settings, some have a brim.
