I liked the design of the rugged desktop organizer, but I needed something that would store my boxcutter while allowing easy access. I also added slots for a screwdriver and a pair of scissors to stand straight up, and added a little front storage, which I am currently using for a tape measure.

I've included the FreeCAD model, which is fully parametrized.

There is a two-peice and single-piece version. I printed the two-piece. Bed supports are required for the small lip on the top peice. No other supports should be required.

I printed this with 10% in-fill and 2 perimeters. The result is VERY sturdy.
