This is a reliable and 3D printable keychain! Please read the user manual carefully to learn the specific operating methods!

Firstly, I strongly recommend adopting a lower floor height, setting up a reasonable support structure, and adding spray-on supports to the model. Secondly, the entire keychain will naturally fuse together after printing is completed - this is precisely the original design intent and the expected effect.

To separate the chain links, simply push them inward gently until the chain links automatically detach from the connected sections. This process requires almost no effort and is very easy and convenient. Finally, the largest chain links at the end are already welded together. You just need to gently pry them open with a little force; if necessary, you can also use scissors to trim them at appropriate places. Throughout the entire process, there's no need to forcibly break the keychain to complete the disassembly. Additionally, to achieve better toughness, I recommend using PETG material for printing first.

I hope you'll like this product!

I wish you a pleasant experience using it!
