Toddler Toy Angular Numerals

thingiverse

This is designed to be 10 puzzle pieces (numbers 0 through 9) that fall through the plate and into the container below. In the United States, the Child Safety Protection Act requires warning labels on packaging for toys containing small parts. A tool called the small parts test fixture is used to measure toy parts. It is a cylinder tube with a diameter of 1.25 inches and a depth between 1 and 2.25 inches, designed to mimic a child's mouth and pharynx. Any object that fits in the tube is considered a small part and must have a label on its packaging indicating it is a choking hazard for small children. This 3D object at its current scale (in inches) contains small parts. The puzzle may be scaled larger but is currently designed for a 3D print bed with dimensions not quite 9in by 9in, with usable dimensions of 6in by 6in. If you have a larger printable area and would prefer to give this toy to a child younger than 3 years, please scale the design accordingly. Also Note: I do not recommend the lesson plan below for very young children; even if it were developmentally appropriate, the use of small beads, buttons, or base ten counting blocks also presents a choking hazard.
