Parametric Table Corner Bumper (Solid & L‑Shape)

Parametric Table Corner Bumper — Solid or L‑Shape, Fully Customizable

This model gives you a clean, protective corner bumper for any table, desk, or workbench. It’s fully parametric letting you dial in the exact fit for your furniture — from chunky workshop benches to thin IKEA tabletops.

You can choose between:

Solid Style

A full corner shell that wraps the top and both sides. Maximum protection and great for homes with kids or sharp metal furniture.

L‑Shape Style

A lighter, edge‑only version that protects the top and outer edges while leaving the underside open. Uses less filament and still provides excellent impact protection.

Features

• Parametric: Adjust bumper size, drop height, wall thickness, corner radius, and edge width.
• Two Styles: "solid" or "l_shape" — both included in the same script.
• Support‑Free: Automatically rotates into a perfect print orientation.
• Rounded Outer Corners: Clean, friendly geometry that’s safe and looks great.
• Beginner‑Friendly: Easy to print in PLA, PETG, or TPU.

Tips

• For baby‑proofing, print in TPU for a soft, forgiving bumper.

• Use double sided tape to attach the bumper to a table.

   

Print Recommendations

• Orientation: Already rotated for you — prints flat on the outer face.
• Supports: None needed.
• Material:
  • TPU for soft bump protection
  • PETG for durability
  • PLA for indoor furniture

Customization Parameters

• bumper_size — how far it extends along the table edge
• drop_height — how far it wraps down the sides
• wall_thickness — padding thickness
• corner_radius — outer rounding
• style — "solid" or "l_shape"
• edge_width — top coverage for L‑shape mode

Everything is cleanly structured and easy to modify.
