Two Pocket Puzzles - Fill the Boxes

thingiverse

Two challenging puzzles present themselves: partially filled boxes serving as targets. A step up from thing:4259734, which used three pentominos, each box now requires four to fill completely. While not overly demanding, the already completed sections significantly reduce the number of attempts needed to arrive at a solution. One puzzle features a diagonal row of filled squares, while the other boasts a set resembling a face.
