The idea is simple: it works as a normal keychain attachment, but the bearing makes it a silent and smooth way to fidget with your keys. The shape is made to fit comfortably around your finger, making it easy to spin, hold, or play with during everyday use.

The design is clean and minimal, while still being functional and satisfying to use.

Assembly / Print info
This model is printed with the bearing inserted mid-print.

Pause the print before the overhang starts, insert the 6003 RS bearing, and then resume the print. Once the print is finished, the bearing is locked securely inside the model, making it feel like one complete part.

No supports are needed, since the bearing itself becomes part of the structure during printing.

Features
• Minimal big keyring design
• Silent way to fidget with your keys
• Comfortable finger-sized shape
• No supports needed
• Secure and snug bearing fit
• Functional print for everyday carry

Fit & performance
The bearing fits snugly into the print and is locked in place once the model is finished. It is designed for smooth, quiet fidgeting while still working as a practical big keychain attachment.

Make sure to pause the print at the correct layer before the overhang, so the bearing can be inserted cleanly before the print continues.
