Parametric Table/Chair Leg Riser/Extender

This is a parametric socket-style riser/extension for tables, chairs, or other furniture with cylindrical legs only.

It allows you to increase the height of furniture while keeping the legs safely locked into a socket.

Parameters

• raise_height (mm): The solid bottom thickness = how much you lift the furniture.
• socket_depth (mm): How deep the furniture leg sits inside the riser (insertion length).
• leg_diameter (mm): The diameter of the cylindrical furniture leg that goes inside the socket.
• clearance (mm): Extra tolerance to ensure the leg fits (0.2–0.4 mm recommended for a well-calibrated printer).
• contour_wall_thickness (mm): The thickness of the outer shell around the socket.

Printing recommendations

• Material: PLA.
• Walls/Perimeters: 4–5 (at least 1.6–2 mm).
• Top/Bottom Layers: 5–6.
• Infill pattern: Cubic or Gyroid.
• Print orientation: flat on the base.

Infill recommendations

The required infill depends on how much weight the risers will support.

Assuming 4 cylindrical legs and 60 mm diameter risers:

⚠ Note: Increasing infill beyond 50% does not significantly improve compression strength.

The walls and bottom thickness are more important for structural integrity.
