How to assembly:
Easy. Print the one plate with all pieces. Stack the key-shaped pieces on the rivet. Thread a string through the hole in the rivet. Let the long end of the string hang from the back side. Secure the rivet by stuffing the small wedge (file attached), a larger knot or a small bead into its head.
You are ready to go.

How to play it (for the kid):
You start winding from the starting notch.
Lead the string from the notch on the left to the correct answer on the right.
Then go under the plate and return the string back to the left side, take the next notch in the row. And so.
After you finish counting and winding, flip the plate around.
The string should match the pattern on the backside.
And if the string does not match the pattern? No worry. Just unwind a bit and try again.
Unsure with the counting? Just try and check yourself. No red mark, no bad grade. Just fun.

Update 02/2024: Added version with flat not-embossed letters for improved multicolor printability
- Added version with flat letters on the face side and flat line-pattern on the back side. Print it with the face down, the quality of the printed letters will be much better. No more oozing, no more blurred text.
- Files for this version have "flat" in the name.
- For Bambulab printers, the *.3mf file with already painted colors has been added.
- For other printers, the *.stl files, the embossed letters and profiles have 0.02mm height, which should be enough to paint them for the multicolor print in your slicer. However such a low profile of the letters won't cause the extra layer during print.

Enjoy ;)

Basic setting should do it.
The design is simple by purpose to make it very easy to print.
No fancy tricks needed. It's simple rookie's print job.
Any easy-to-print material will do (PLA, PETG or so…).

There are two variants:
- files for multicolor print with shallow embossing profile.
(STL files with basic shape, already colored full 3MF profile for the BambuStudio)
- files for unicolor print with more prominent embossing profile.
