3D Tetromino Puzzle Box (customizable)

I designed this 3D brick puzzle essentially as a spin on the well-known Tetris formula: Try to fill up the box completely without ending up, well, blocked. And it turns out this can be a fun and tricky brain teaser!

Simply print the box (and optionally, the lid) and a total of 16 tetromino bricks. Which ones you choose is up to you - I printed three of each, plus a fourth T block. Almost any combination of bricks should be able to fill up the box. And of course, there are many different solutions for any combination of bricks.

In addition to the 4x4x4 box, I also included a flat 8x8 box, which of course works with the same amount ot tetromino bricks. The lid for the flat box is just a frame - the filled-in 8x8 box can look nice as a wall decoration, too!

Using the OpenSCAD file, you can also generate puzzle boxes of any size you like. Just make sure the total number of blocks (X*Y*Z) is a multiple of four.
If you want to scale the bricks up or down, I recommend regenerating the puzzle box with the resulting block size in OpenSCAD.

Happy puzzling!
