This is a system designed to be used as first puzzle, mostly for babies/toddler ages 6 months to 2 years. The system is designed so that it can be extended in the future, or peaces mixed, re-ordered so it's more interesting and engaging for the child.
For now the following base shapes/inserts are available:
For future it's planned to add more shapes, such as:
Possible combinations for print
For babies from 6 months start with a single puzzle. Print one base and one insert (circle is probably the easiest for them as there is no direction when inserting) and print the puzzle edges so that it's padded with nice round edges.
As your child grows you can print more bases/inserts, like rectangle or triangle and add them to existing peaces.
Multi colour prints are possible by changing filament on particular layer height (see picture), for both the base and the inserts. On the base this creates a contrasting colour between the shape and base. For insert this creates a contrast for the handle, so that the child recognises more easily where he or she should handle the piece.
