Color Coded Key Sheaths

This key sheath helps identifies your keys, protects your pockets, and also makes them easier to to use. With just three filament colors you can create 6 different color combinations for identifying your keys. And with the pointy end enclosed in the sheath, you save wear on your pockets. Finally, as a bonus, when the key is deployed, you get added leverage if you've got weak, cold, or just plain tired hands.

This is designed for Kwikset or Schlage keys that are 52mm long, 2mm thick, and up to 27mm across the head. If your key is a little bigger or smaller, you should be able to make small scaling adjustments to get the perfect fit.

I've included two different versions: one plain and one with a small loop for attaching a ring or beaded chain.

Printing
This prints in PLA with no supports. Use exactly 0.2mm layers so that the built-in break-away support will come free easily. But if you scale the Z axis, also scale the layer thickness.

To assemble, just flex the fingers of the insert apart and click your key into place. Then slide the key and insert into the sheath.
