Concentric shape puzzles for babies and toddlers

thingiverse

Various concentric shapes that can be stacked horizontally. I got the idea from a Montessori toy set which only had the hexagons. The shapes are loosely based on my shape tray puzzle [thing 5482400](https://www.thingiverse.com/thing:5482400) (with the peppa book) and the original [thing 3388702](https://www.thingiverse.com/thing:3388702). Each shape has 6 STL files, one for each of the 5 pieces (suffixed 1 through 5), and one with all the pieces together suffixed with the plural. There are 12 shapes: circle, cross, diamond (rhombus), flower, heart, hexagon (the bestagon), oval (ellipse), pentagon, rectangle, square, star, triangle. The outer/larger pieces tend to be thin for their size so preferably print with thick walls or more infill to make them sturdier. I opted for thicker walls at 5 lines and just 10% infill, this prints faster and pieces are more dense where they are thinner.
