3D model descriptionA toy designed by a cognitive psychology student who has been involved in science communication for years(haha yes, me, but in 3rd person).

This toy is a sand sieve.

Children who play with this toy will learn how filters work: they'll see sand magically appear inside the sieve when they press it against the sand, but if they use it as a shovel, they'll discover that the sand will fall out of the holes, leaving only the larger objects in the cat's mouth: shells, pieces of wood, and leaves.

Education according to the constructivist model:Children learn more easily if they can experience things directly and interactively. It's very important that children develop creativity and problem-solving skills from a very young age for their future well-being!

Challenges for the child:Try to help the child discover how the dynamics of play change if the sand is wet, almost dry, or completely dry.

3D printing settingsPRINTING SETTINGS:no supports, no brim.Use ABS (300mm/s fast ABS is ok too),40% infill (child-proof...).It's normal to find a file called version two, v2 this model is already version 2, which means I made it stronger and easier to print while testing it.

MULTICOLORYou can use a CFS (or AMS or MMU3): import both the models (frame and parts) as a single object with different parts (or use FULL cat with separated parts.stl), it will be easier to manage different colors.No CFS? No problem: print the main frame, then change the filament and print the other 11 files (cat_color_details_number.stl). Assembly if you are not using a multicolor automatic system: use a bit of glue.

Commercial license:Yes, you can print and sell this 3D model.You can also use it for renderings and video games!You cannot redistribute the individual model or its parts;you can only sell physical prints, videogames or renderings.
