Sharpening stones apex blanks storage container box (mk.II)

## UPD (2021-09-16): [Newer reworked version mk.III](https://www.thingiverse.com/thing:4969248)

It's a storage box (container) for apex-like sharpening stones (or any other rectangular stuff).
Newly created from scratch, features lightweight see-through design, nice fit, snap-on cover and additional numbers to store each stone on it's own place. Also there are utility windows on the bottom to push those out, if fit too tight =)
1.4mm thick walls with 2mm bottoms for sturdy construction.
