These molecules are made up of basic shapes using Tinkercad. I am not a Chemist, but I thought this was a fun idea so it's more a representation of the molecules and not meant to be 100% accurate.

It can sometimes take a couple tries to get these printed right because you want to make sure they stick on the first layer and that you get good infill on the top and bottom. Doing ironing can help on the top.

The following molecules are included:

• Serotonin - well-being and happiness
• Dopamine - reward-motivated behavior (also sometimes considered the pleasure-seeking molecule)
• Adrenaline - causing increased heart rate, it is the molecule of energy
• Caffeine - is a psychoactive drug, known for causing awakeness
• GABA (gamma-Aminobutyric acid) - reduces excitability / anti-anxiety
• Whiskey is whiskey - this one was made by request in the past
