WrapUps, the complete bundle (learn to count +addition, -subtraction, *multiplication, /division) , Unicolor print embossed letters

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

Finished prints for sale
Don't want to bother with printing? You can buy the ready-made multicolor prints on the website of our workshop:https://www.ma3d.cz/obchod. For custom colors and shipping outside the Czech Republic, please contact me, we can solve it individually.

See here what the front side looks like with the letters and the back side with the line patterns:

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.

See assembly (steps are identical for one-color and multi-color version):

One-color or Multi-color?
- Thanks to embossed profile of the letters and lines, it works perfectly when printed with just one color. So, any simple printer is just perfect for the job, no limitations.
- Sure you can paint it in your slicer and print it as multi-color. However, we have other models optimized for the multicolor print. They look awesome. Check here: https://cults3d.com/:1830777

Check the multi-color version:

Files overview:
- STL models of the main key-shaped pieces.
- STL model of the rivet to assembly the the set.
- STL model of the small wedge to secure the rivet in place (also to secure the string in the rivet)
- 3MF project for BambuLab printers containing all the above models organized in the 4 print plates. It includes some print settings (easy to snap off supports for the rivet, ironing of the top letters faces)

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…).
