The Procrastinator Puzzle - 21 puzzles in one set!

There are three pieces made up of 4 units and six pieces made up of 5 units. Use all the 4 unit pieces and any combination of three of the 5 unit pieces to make a 3x3x3 cube. There are 20 possible combinations to make. The 21st puzzle is to pack all 9 pieces into the box! One of the photos lists the number of solutions for each combination of pieces and the relative difficulty. You might want to download it for reference. I have a burrtools file for this puzzle if you want to see every one of the solutions.
