The teaching aids were designed as part of a long-term pupils project of the school ZŠ nám. Republiky in Znojmo, Czech Republic – Printing of the teaching aids on a 3D printer. In order for pupils to be able to create a 3D model using design programs, they first had to master the issue of the teaching aid. Thanks to the new equipment, a 3D printer, they were able to transform the 3D model into a real form, and at the same time create more copies for easier application of the teaching aid in the class. Pupils were able to present teaching aids (the cube, the map and the letters) to their classmates, thus proving that they handle the topic very well.
