Annular Heat Chamber

Create a hollow cylindrical annular heat-chamber component based on the reference image. The part should resemble a short cylindrical metal chamber with a large concentric circular opening through the center and a broad annular top flange. Geometry requirements: Main body must be rotationally symmetric. Create a cylindrical outer wall. Create a large circular opening through the center. Create a flat annular top flange extending inward from the outer cylindrical wall toward the central opening. Around the central opening, create a short downward cylindrical inner lip/wall, similar to the reference image. The outer cylindrical wall extends downward below the top flange. The bottom remains open. The center remains fully open. Add two horizontal rows of evenly spaced oval ventilation holes around the lower outer cylindrical wall. All ventilation holes must pass completely through the outer wall. Align and distribute the ventilation holes evenly around the full circumference. Use smooth, clean transitions between the top flange, outer wall, and inner cylindrical lip. Do not add unnecessary decorative geometry. Material thickness: Use a uniform wall thickness of exactly 0.5 mm throughout the entire component. Outer cylindrical wall thickness: 0.5 mm Top annular flange thickness: 0.5 mm Inner cylindrical lip thickness: 0.5 mm All formed or bent sheet-metal regions must maintain the same 0.5 mm material thickness. Do not create thick or solid sections. The component should behave geometrically like a formed thin-sheet-metal heat chamber. Parametric dimensions: Outer diameter: OD Overall height: H Central opening diameter: ID Top flange radial width: FW Inner downward lip height: LH Ventilation hole width: VW Ventilation hole height: VH Number of ventilation holes per row: N Vertical spacing between ventilation rows: VS Keep all of these dimensions parametrically editable. Ventilation holes: Use rounded-slot or horizontal oval-shaped holes. Holes should follow the curvature of the cylindrical wall. Distribute them evenly around 360 degrees. Create two vertically separated rows. Stagger the second row relative to the first row if necessary to resemble the reference component. Construction requirements: Produce one continuous connected CAD component. No overlapping bodies. No disconnected geometry. No internal solid filling. Maintain the 0.5 mm wall thickness after all cuts and openings. The final geometry should be manifold and suitable for export to STEP/STL or further manufacturing design work.
