Vinyl chloride is a colorless, flammable gas primarily used in the production of polyvinyl chloride (PVC). PVC is an incredibly versatile and widely used plastic, found in products ranging from pipes and window frames to flooring, wiring insulation, and packaging. The conversion of vinyl chloride into the stable PVC polymer is essential, as the monomer itself is a hazardous substance. It is a known human carcinogen, with chronic exposure linked to a rare form of liver cancer (angiosarcoma), as well as neurological and immune system effects. Due to its toxicity, strict regulations govern its production and handling in industrial settings.

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.
