Rounded Swiss Key Chain
Keep your house keys safe and compact, uses under 10g of filament.
I designed this key chain 6 years ago, and just dug it back up because my original finally broke.
- Uses 3 #2 machine screws/nuts
- Small nylon washers for smooth key access
- Great for 4 keys or more. I carry 6, and its 20mm thick
- Print in PETG for durability.
- Variable layer height gives it a pleasant surface texture.
