Flexi hexagonal coaster

Hello guys,

because I love practical things and after a success of my not so practical [Tetrahedron Chainmail Fabric] (
https://cults3d.com/en/3d-model/fashion/tetrahedron-chainmail-fabric-lukes3d) I thought what kind of useful thing can I make it
into?

[creation tetrahedron-chainmail-fabric-lukes3d]

So I came up with this design. I adjusted the chainmail so the gaps are not as huge, flattened the tetrahedrons and made it into hexagonal shape. I also tried to get more contact surface on first layer.

For those of you wondering what kind of filament this is - I used 3D Jake Deep Space Magic PLA to get that amazing looking gradient. I would not recommend PLA if you want to use it with hot mugs as it could reach glass transition temperature, instead use PETG, ASA or ABS. And one last thing, I used concentric top fill pattern to get the tetrahedron-ish look.

NOTE: This is a challenging print and will require flawless bed adhesion and good printer calibration, particularl
