Strong 360 Swivel S Hook

I wanted a hook that could fully rotate, so I designed this one to swivel a full 360°. It prints cleanly with no supports and has surprisingly strong tensile strength. With PLA, I’d rate it around 10–15 lbs for long-term use, though tougher filaments will handle more.

It might feel a little snug right off the printer. Just give it a firm twist and it’ll free up. I tuned the tolerances to keep wobble to a minimum while still rotating smoothly.

Key measurements:

• 13.5mm tall at the center
• 15.8mm (5/8") max hook opening
• 21.6mm (<7/8") hook ID
• 9.5mm (3/8") max hook diameter
• 107mm (4.2") long
