PAX Designs | "The HangHero" Parametric Hook

Short description  

The HangHero is a parametric, 3D‑printable U‑hook designed for strength, versatility, and easy customization. It supports both screw‑mount and bracket modes, offers an optional second hook, and is tuned for being used in MANY different ways.

Key features

• Parametric control — change overall size, thickness, spacers, screw diameters, and bracket options with simple top‑of‑file variables.
• Two mounting styles — classic screw‑hole mounting or a bracket clip for hanging over doors or tubes.
• Optional second hook — add a secondary angled hook for extra capacity or multi‑use hanging.
• Print‑friendly details — countersunk screw heads, tolerances, and high‑resolution facets ($fn) are exposed as parameters.
• Strong geometry — designed with structural shortcuts (stiffness, hulls, and rounded transitions) to maximize load capacity while minimizing material.
• Customizer ready — parameter ranges and comments are included so users can quickly generate custom STLs online.

What you can customize

• Hook size and thickness — scale the main U and print height to match your needs.
• Spacers — control vertical spacing between hook elements and screw placements.
• Screw settings — set screw diameter, head diameter, and head depth with tolerance for easy fit.
• Bracket options — choose square or rounded brackets, add a safety screw, or enable a rounded tube clip.
• Cosmetic options — toggle the triangular tip, rounded top, and screw holes on or off.

Printing and usage tips

• Disable preview helpers before exporting STL (preview geometry is included for visualization only).
• Material — PLA works for light loads; PETG or ABS recommended for higher strength and outdoor use.
• Orientation — print the hook lying on its side as intended by the model for best layer strength.
• Tolerance — if a screw feels tight, increase the tolerance parameter slightly and re-export.
• Layer height — use a moderate layer height (0.16–0.28 mm) and 3–
• 4 perimeters for a good balance of strength and print time.
• Infill — 15 - 25% for optimal strength (recent experiments show that optimal infill amounts are stronger than extremely high infill!)
