Block Z (Goh Pit Khiam) - IPP 39 exchange puzzle (FREE shipping)

All pieces were laser-cut. The pieces and frame's colour will be random.

Objective: Fit 1 tetromino and 4 dominoes into a 4x4 box as follows. The pieces must go through the bottom hole.

Design concept from Goh Pit Khiam: When I first designed The Restricted Zone, which was a similar puzzle where pieces fill the box entirely, I was curious whether I could create a "2D caged-burr" but with holes, much like high-level burrs. One of the interesting configurations is this puzzle. The packing is very loose, but the pieces do not seem to want to come off that easily. It feels very much like a disentanglement puzzle.
