Puzzle difficulty:
Different for the various problems. From medium to expert.

Printing instructions:
The hexominoes are modeled using PuzzleCAD: https://www.thingiverse.com/thing:3198014. On top of a usual hexomino (in blue) is a copy reduced in size (in white). The slicer automatically finds the correct height for a filament change.
Prints are fine with no supports, but need a manual filament change.
I printed the puzzle in PLA at 0.1 mm layer height.
