This shell can help you to organize your keys if print it in different colours. Just print two pieces and assemble it with one click. Designed to fit APECS key (like on photo).
I printed them with ABS and it worked quite well.
Designed with Inventor, so you can customize attached .ipt file to add some own text on outer side.
