Top Cap
Top Cap adds solid infill layers at the top of the print to close the opening, mirroring the behavior of Bottom Cap with the same fill choices. Use it for enclosed vessels, lamp housings, or any design that should finish with a flat or patterned lid surface.

Parameters
Solid Layers- Count of solid top layers (1–20).
Fill Pattern- Infill style: Rectilinear or Concentric (discrete choice).
Center Hole- Enable or disable a circular opening through the cap (boolean).
Hole Ø (mm)- Diameter of the center hole when enabled (0–100 mm).
How It Works
Solid layers are emitted at the top of the model so the upper opening is covered consistently with the selected fill pattern. The implementation matches Bottom Cap’s overlap behavior, which keeps strength and appearance aligned between the two ends of the part.
An optional Center Hole preserves a passage for cords, wicks, or airflow while the surrounding layers still form a closed roof.
