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.
