Keyring Split Ring Opener – No More Broken Nails!

Attaching split rings to keychains can be a real hassle – you have to wedge in your fingernail and risk damaging it. This simple tool eliminates that problem!

🔹 How does it work?
Just slide the opener into the split ring to slightly widen it. Then, slide the ring onto the keychain and remove the tool. That’s it – quick and painless!

🔹 Features:
✔ Fast print – only ~4g of filament
✔ Durable – I’ve used it for hundreds of keychains, and it still works perfectly
✔ Easy to use – great for anyone who frequently attaches split rings

🔹 3D Printing:
I recommend PLA, but other materials should work too (I haven’t tested them yet).

Download and print – it’s a small investment that saves a lot of frustration! 🔑💡
