My kids are absolutely addicted to keychains. Their backpacks probably have an extra 5 pounds of keychains dangling off them. One of the first things we tried when we got our ToyBox 3D printer was try to make our own. I found some designs worked and some didn’t, so here are my favorites.

For all of these, I have the original credit to the designer who made them and shared. Most of them came from Thingiverse. However, I am also sharing the ToyBox link to how I have adjusted them. Many are rotated and scaled, as well as I had to add the keychain part in Tinkercad to a few.

I put this one first because I made it from scratch in Tinkercad and was very proud of myself. We printed 50 of them for my kid’s class.

This keychain is a champ. I have never had problems printing it and a bit more durable than some of the other Flexi ones.

Keychain Clasps

One of the keys to this is having good keychain clasps. I found these on Amazon and work well for my kids because their fingers can open/close them.
