Phân tử Caffeine (Caffeine Molecule)

I generated this model with https://pubchem.ncbi.nlm.nih.gov/ and https://3d.nih.gov/ and printed it with my mk3s+ and mmu3. I'd recommend to use different colors for the molecules, I also uploaded the painted project file.

Some settings are changed for the best results, such as the z gap between the support and the model, the flushing volumes, infill, etc.
