Description:
These replacement pins repair the locking mechanism of the original Slinger tennis ball pickup tube.
The factory plastic locking studs can break quite easily over time, especially during transport or repeated assembly and disassembly. Instead of replacing the entire tube, this repair allows you to restore full functionality with a simple modification.
The repair process is straightforward:
- Remove or grind off the remaining broken locking tabs.
- Drill a 6 mm hole at the original locking position.
- Glue the printed replacement pins into the drilled holes.
After installation, the tube locks together securely again and works very similar to the original mechanism.
Features
- Repairs broken Slinger pickup tube connectors
- Replaces fragile original locking studs
- Cheap and easy repair
- Restores full functionality
- No need to replace the complete tube
- Simple installation with basic tools
Installation
- Remove the damaged or broken original locking tabs.

- Verify proper movement and locking function.
Printing Notes
