Shelf with lockable boxes

I have to much screws, hexagonal nuts, washers and more. I like to organize these now.
One shelf holds nine boxes, which you can hangup or standing.

You can print multiple pieces and use them to create a large shelf.

Sizes:
- Boxes round 85 x 65 x 40 mm
- Boxes small round 70 x 55 x 40mm
- Shelf round 182 x 152 x 57mm

The box with handle is not printed yet. If you want, please let me know if it works.
