The Simple Puzzle

:UPDATE: 12/24/2021 i noticed i had learned a great deal since getting a printer on my workbench and resized some pieces. Also was told i forgot to add the sphere.

For a while I wanted to design a toy similar to one i grew up with where you put shapes into other interlocking shapes.
After printing there will be small parts so be mindful of what your kid or adult friend does when left alone with small plastic toys.

Height is 110 ~ 150mm fully assembled
i tried to get the plates close to 1cm tall because any smaller would result in tiny interior shapes any bigger would = print size issues; and i didn't want this thing to take weeks to print.
