FIT (Packing Puzzle)

Puzzle Name: "FIT"
Type: Packing Puzzle
Here's the first puzzle that I designed! Inspired by the brilliance of Stewart Coffin, and designed with BurrTools, the goal of the puzzle is to cram all 7 pieces into the box.
The box's dimensions are 4.0 x 4.2 x 2.8 units.
In its solved state, all the pieces will either be below or at the lip of the box. Nothing will stick out. Not even a little bit. See the photos for an example of what is not a solution.
Please let me know on the comments below on your thoughts about the puzzle.
Have fun!
