This design is for a replaceable steel wire brush handle, with a main cylindrical diameter of 50mm, suitable for steel wool balls of 50-80mm specifications. Users can scale the model according to actual needs (Note: excessive reduction may lead to easy breakage of the barbs).

The core advantage lies in the modular replacement function—when the bottom barbed disc partially breaks, this component can be directly printed separately for replacement.

Assembly Tips:

1. The two components fit snugly under standard printing conditions
2. If the connection is loose, the following enhancing measures can be taken:
   - Add 3D printed fuzzy texture to the contact surface
   - Apply glue
