Desk Chair Caster Stopper

This slip-on stopper that securely prevents rollerblade-style desk chair wheels from rolling, ideal for use on smooth surfaces where chairs roll when you need them to remain stationary. Designed for TPU printing to provide durability, floor protection, and slight flex for easy installation.

Design Features:

• Form Factor:
  • A U-shaped cradle that clips over the roller blade wheel from the side
  • Prevents forward and backward rolling by locking the wheel in place
  • Low-profile design to minimize tripping hazard
• Wheel Compatibility:
  • Fits standard roller blade-style caster wheels
  • Slightly oversized internal channel width for easy snap fit
  • Internal radius to accommodate most roller blade wheel profiles
• Stopper Base:
  • Flat, textured base for floor grip
  • TPU chosen to reduce floor marking
• Material & Print Settings:
  • TPU (Shore 95A recommended): Provides flexibility for installation and prevents cracking
  • Print orientation: base flat on bed for stability

Usage:

• Slide or snap the stopper onto each caster wheel.
• The TPU flex allows easy installation while maintaining a tight grip.
• Removes cleanly without damaging wheels or floors.
• Great for desk chair sim racers!
