My grandma have arthritis and she couldn't use her key anymore.
Because of that she was afraid to leave her home.

So I designed this big and easy to handle cap for her key.
Now she can go out as much as she want!

I recommend printing in ABS and using acetone to join the 2 parts.
That way it will become very strong.

This is designed for Vachette V5 key (see picture) but the Freecad source file is provided, so you can easily adapt to any key

use at least 50% infill to not have it too brittle.
