Overview:

We have several keys that look identical, so it can be a pain trying to find the key to unlock the house at night.  I designed this cover to fit a Schlage-68 style key.  To install it, slide one end of the key in, then push the cover over the other end.

I’ve included my Fusion 360 design, so you customize it how you wish using the included parameters.  The design includes a modeled key as well.

Printing:

I recommend printing these in TPU filament.  No supports required if printed in the orientation shown, but I recommend two perimeters.
