Puzzle description:
There are 10 different one-sided checkered terominoes which should be packed into a square or a rectangle with the correct checkerboard pattern.
The first goal of the puzzle is to select nine of the ten tetrominoes and pack them into a 6x6 square. The tray contains a space for the spare tetromino.

Printing instructions:
The main color (usually gray or black) is used for the pieces and half of the caps. A second color is needed for half of the caps for the checkerboard pattern. The caps can easily be snapped onto the pieces.
For the 10 pieces you need
A tray for the 6x6 checkerboard with space for a spare part also is provided. The tray was designed using PuzzleCAD: https://www.thingiverse.com/thing:3198014
Prints are fine with no supports. Snap the caps onto the different parts as in the picture. The caps are printed upside down, so the pieces will have a very flat surface.
Be sure to use the correct checkerboard pattern for the pieces.
I printed the puzzle in PLA at 0.1 mm layer height.
