Customizable Flanged Pipe Adapter

This OpenSCAD script is designed to generate a customizable mounting plate with an integrated pipe adapter. The design is modular, allowing users to define the base dimensions (size, thickness, and mounting holes), the geometry of the pipe (diameter, wall thickness, and total height), and specialized features like O-ring gaskets. The design is parametric, meaning you can easily adjust the geometry by modifying the variables without needing to edit the underlying code structure.

Plate Parameters

These define the physical dimensions of the square base plate and the mounting features.

• plate_size: The side length of the square base plate (mm).
• plate_thickness: The vertical thickness of the plate (mm).
• corner_radius: The radius used to round the corners of the plate (mm).
• hole_diameter: The diameter of the through-holes for the mounting screws (mm).
• hole_offset: The distance from the center of the mounting holes to the edge of the plate (mm).
• countersink_diameter: The diameter of the recessed area for the screw heads (mm).
• countersink_depth: The depth of the countersink recess from the top surface (mm).

Pipe Adapter Parameters

These control the geometry of the central pipe structure extending from the plate.

• bottom_inner_diameter: The internal diameter at the base of the pipe.
• bottom_inner_thickness: The wall thickness of the pipe at the bottom.
• bottom_height: The height of the bottom section of the pipe.
• top_inner_diameter: The internal diameter at the top section of the pipe.
• top_inner_thickness: The wall thickness of the pipe at the top.
• top_height: The height of the top section of the pipe.
• full_height: The total height of the entire pipe structure from the plate surface.

Top Gasket Parameters

These manage the configuration of an optional seal or gasket at the top of the pipe.

• top_gasket_z_pos: The vertical position of the gasket relative to the top of the pipe.
• top_gasket_dia: The cross-sectional diameter (thickness) of the gasket ring.
• top_gasket_milling: A fine-tuning adjustment for the gasket's radial position.
• top_gasket_type: Selects the operation: "out" (adds a ring), "no" (none), or "mill" (cuts a groove into the pipe).
• top_gasket_position: Determines if the gasket is placed "external" (outside the pipe wall) or "internal" (inside the pipe wall).

Support Parameters (Chamfer) [added June 08, 2026]

These manage the configuration of an optional seal or gasket at the top of the pipe.

• use_chamfer:  enable/disable chamfer.

• chamfer_size:  The chamfer size (mm).

   

Resolution

• fn: The number of fragments used to render circular and curved objects. A value of 128 results in a high-resolution, smooth finish for 3D printing but increases rendering calculation time.
