Hexagonal tiling puzzles with daily different goals

• Arrange the pieces so that cells of your preferred day are visible.
• You can enjoy the puzzle every day. It has daily different goals.
• I confirmed there is at least one solution for every case using solver program.
• The smaller versions can be solved without flipping pieces, so you can enjoy the puzzle three times every day.

There are three versions with different difficulty levels

• 61 cells : difficult version with cells of months, dates and days of the week. There are blank cells to fill the board. 
• 43 cells ver.1: relatively easier and smaller version with 43 cells of months and dates. No blank cells. 
• 43 cells ver.2 : less symmetry (= more independent filling patterns), the easiest version.

Smaller versions (43cells ver.1 and 2) are solvable even if the pieces are not reversed.

• You can enjoy the puzzles three times a day. 1st : using both sides, 2nd : a single side only, 3rd : all pieces reversed
• Print all pieces with two layers (different colors on top and bottom).
• That might make the puzzle more difficult.

The difficulty of this puzzle is relatively high, and not for kids I think. Typically the larger version might take around 10 - 60 min to solve by adults.

note : If you use "piece43.stl" for "board43-ver2.stl", there are some unsolvable days. Please use "piece43-ver2.stl" for "board43-ver2.stl". (Contrary, you can use "piece43-ver2.stl" for "board43.stl".)

How to make

• To give a different color to the texts and grid lines, use "Pause at height" function of your slicer (see the picture above, for Cura slicer) to switch the material during 3D print. Change the material at height=1.1mm (smaller verson) or height=1.5mm (larger version).
