This 3D printable Snap-Lock Keychain Connector Set includes four versions:

a  rounded-corner design, a square version, fuzzy-skin version, and a shopping cart coin/token.

Each connector consists of two interlocking pieces that click together securely and can be pulled apart easily.

 

Both parts feature a hole for key rings or chains, making them perfect for organizing keys, tags, or small accessories.

I personally love the fuzzy-skin version — it has a nice tactile feel and I use it daily with my portable USB drive.

These print cleanly in PLA, and while supports may be used, they’re easy to remove after printing.

Recommended print settings:

• Material: PLA
• Layer height: 0.2 mm
• Supports: easy to remove
• Infill: 100%
