Cyclohexene (C₆H₁₀) is a colorless liquid hydrocarbon with a sharp odor. As a cycloalkene, its six-carbon ring contains one double bond, which is the center of its reactivity. Unlike the stable "chair" conformation of cyclohexane, cyclohexene adopts a less stable "half-chair" shape. It serves as a crucial intermediate in industrial synthesis. For instance, it is used to produce adipic acid, a key monomer for making nylon. It is also a precursor for cyclohexanol and cyclohexanone, which have applications in producing pharmaceuticals and insecticides.

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 atom 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.
