Dichloromethane (DCM), also known as methylene chloride, is a chlorinated hydrocarbon that exists as a colorless, volatile liquid with a sweet, chloroform-like odor. It is widely used as a solvent due to its ability to dissolve a variety of organic compounds and its relatively low boiling point, which allows for easy removal. Its major applications include paint stripping, degreasing, and as a process solvent in the manufacturing of pharmaceuticals and other chemicals. It was also historically used as a decaffeinating agent for coffee and tea. Despite its utility, DCM poses health risks; it is classified as a potential carcinogen, and acute inhalation can lead to nervous system damage.

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.
