WrapsUp, the complete bundle (learn to count +addition, -subtraction, *multiplication, /division) , Multicolor -look print with flat letters

Learn to count by self-evaluation
Kids can learn on their own without being corrected by the boring teacher.
With the Wraps-Ups, the children evaluate themselves and can try it again for better result with no hassle.

Here is how it looks from front and back:

How to play it and count with it (for kids)
You start winding the string 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.

How to assembly:
Easy. Print the plate with all the pieces (ten key-like-shapes, rivet and small wedge). 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.
You are ready to go.

One-color or Multi-color?
- This is version for multicolor print. With Bambu Studio, you can open the 3MF file with already colored models and just press the print button.
- The 3MF file for Bambu Studio has a middle layer added in a contrasting color. This way you can even print it from some semi-transparent filament and the solution on the back won't show through to the quiz on the front.
- For other printers, the STL files have letters and lines embossed with a height of only 0.02mm. That’s enough so the shapes can be recognized and colored in common slicers. Such shallow relief allows the colored symbols to be printed at the same layer as the surface around them. You can achieve good-quality multicolor prints by orienting the model with this surface down (where one layer contains all the color graphics) on the bed. This is a neat trick for printing text and logos.

• If you are limited to simpler monochrome printing, don't worry. Here is another model with embossed letters and optimized for simple monochrome printing: https://cults3d.sitegames.net/:1830368

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…).
