Needed a small box for my scalpel and blades, the one that's available was too narrow for my scalpel. I made one that's wider and longer to put most sizes of small scalpels. In Babo system the size is 5x1 (150x30mm).

This one has 15 blade pockets, with different depths, to accomodate different sized blades. They are not made to be snug, so they are easy to remove, as they are close to each other.

The pics showing the real life part shows version 0.1, the one uploaded is slightly different:

• I made a few shallower pockets deeper
• Widened the space to pick up the handle. You can also push down on the back of the handle to lift up and pick it up.
• Changed name to Scalpel

There's also a space for dull or broken blades, if you don't have anywhere to put them safely, (although after printing looks like it might be too shallow to put larger blades and close the system's lid).
