Slinger Tennis Ball Tube Replacement Pins

I have already found replacement pins for the Slinger tennis ball tube on MakerWorld. These generally work well, but the locking tabs on the counterpart need to be removed. Since I didn't want to damage or permanently alter the original part, I designed my own replacement pin.

Assembly:

• Drill out the areas where the original pins broke off with a 6mm drill bit.
• Glue in the printed replacement pins with standard superglue.

That's all there is to it. The repair is quickly done, and the tennis ball tube is fully operational again.
