The safety ball is inserted into the trailer hitch (standard 50 mm coupling) and prevents it from being mounted onto a tow ball. It serves as a simple but effective protection against trailer theft.

 

 

 

🔹 Features:

  • Protects the trailer against theft – prevents coupling to a tow bar.
  • Recommended ball diameter: 48 mm – fits most trailer hitches.
  • Top grip (“knob”) for easy removal by hand.
  • Possibility to add custom text on the flat surface (e.g., address or phone number).
  • Easy to 3D print with light or simple supports.

🔹 Materials:

  • Can be printed from PLA, PETG, ABS.
  • For outdoor use, more durable materials are recommended: PETG, ASA, ABS+, or PC.
  • For better weather resistance, darker colors and UV-stable filaments are recommended.
