Adrenaline

Adrenaline, also known as epinephrine, is a hormone and neurotransmitter famous for its central role in the body's acute stress or "fight-or-flight" response. Produced by the adrenal glands in response to danger or excitement, it rapidly prepares the body for physical action.An adrenaline rush causes the heart rate to accelerate, blood vessels to constrict to increase blood pressure, and airways to dilate to boost oxygen intake. It also increases blood sugar levels for a quick energy surge and can decrease the body's sensitivity to pain. As a medication, adrenaline is used to treat severe allergic reactions (anaphylaxis), cardiac arrest, and asthma attacks.

Notes

• If you happen to break something, use superglue to fix it. It will make the broken part even stronger.
• I decided to go with the ball-and-stick type, as it is easiest to color, is rigid, and looks awesome.
• The model represents the major resonance contributor.
• I oriented the model for optimal strength/waste/time compromise, but if you decide to reorient it, try to avoid placing bonds along the Z-axis, as they will be very easy to break.
• Supports removable without too much worry of damaging model if you are careful with scalpel and do of paper-sanding afterwards.
• You can use PETG as support material (don't forget to set the heatbed to 70 °C!) and PLA for the model itself (the support then come off much easier). For extra swag, use PLA support filament or PVA as supports.
• Recommended colorization is based on the Corey–Pauling–Koltun (CPK) palette (Figure 1). To quickly change colors, use the settings depicted in Figure 2.
  Alternatively, if you want to save filament and time, print the model in full-white and paint it with a permanent marker.
