Cuboctahedron Magnet Box

1.  The Idea 

I have always loved geometry and one of my favorite models is the Sierpinski pyramid made by ricktu you can find here https://www.thingiverse.com/thing:1356547 

I was browsing polyhedra on Wikipedia looking for examples that had square faces so I could glue the pyramids to it, and found the cuboctahedron. 

So I opened Fusion 360 and got to work creating one, and a few minutes later had something to print! But I quickly realized that I would have to use supports or trust a big bridge, and i don't like those options, so after thinking for a second I noticed there was a perfecet symmetry line to split it in half. 

The only thing left was to figure out how to keep it together, so i added some places for magnets and voila, a cuboctahedron magnet box!

2.  Print Info

The cuboctahedron was printed on a cr10v2 with a .8mm nozzle, .4mm layer height but the model should work with really any setup.

The magnet holes are 6.5 to fit 6mmx3mm magnets so there's room for glue.

The pyramids are the pyramid4 option printed with a .6mm nozzle scaled up to 150% so i could print them in vase mode.

The faces of the cuboctahedron are 41mm to match the base of the scaled up pyramid.

This model can probably be scaled down to fit the 100% pyramid but might need a .6 nozzle or smaller, I haven't tested it yet

3.   Build Info

My first try with superglue didnt go very well, I dropped it after it was dry and they all fell off. JB weld or other epoxy might work better, but what I did was take my soldering iron and set it to 200c and welded the edges together. I think this is much easier and will hold better.

Filament used is Amolen Glitter Rainbow https://www.amazon.com/dp/B09F574SST?ref=nb_sb_ss_w_as-reorder-t1_k0_1_7&=&crid=4VYOUG02YGK&sprefix=amolen%2B&th=1
