1. Grouped the stl files by colour in case you're interested in using my colour combinations (6 colours). The shapes also form a neat rectangular stack.
Using my colour combination maximizes the number of parts on the printbed, so most colours only need one print.

2. Also included the shape groups in case you prefer to make your own colour pattern.
I'd like to try printing in monochrome (two triangle .stl printed in both black and white, then mix them to create an alternating pattern).

I consider the model to comply with the greater than 1.25" criteria if printed at 100% scale,  complying with choking hazard guidelines: https://www.ecfr.gov/current/title-16/chapter-II/subchapter-C/part-1501/section-1501.4

I recommend printing the triangles using a brim to ensure they don't warp off the bed.
Also, I recommend sanding off any edges before letting kiddos play with them.

The shapes are interchangeable (rectangle parts fit into square, etc) for more creativity and learning.

Enjoy!
