A drink coaster in the shape of the coffeine molecule, with all it's atoms.
This version is made for a dual extruder setup, will also work with a single extruder, but the Oxygen atoms won't look that nice. If printed with an according material (ABS/PETG/NGEN) is able to withstand a cup with hot beverages.
You may want to scale the model down a bit according to your needs.
does not matter PLA for cold drinks, PETG or similar for hot ones
for hot drinks 100% but depends
as you wish
Dual extrusion highly recommended!
