Mini-Quadrat-Puzzle

Another nice little puzzle I was offered as short on Youtube:

Because I didn't find this puzzle anywhere else, I'm not even sure, what's the name of the puzzle or who invented it.
So I called it Mini-Quadrat-Puzzle.

The goal is, to also insert the mini square in the basis, so that all 13 parts fit :-)

I recommend to use at least 2 different colours (for the basis and all other parts), better three, but for the parts You may combine all sorts of colours.

You'll need
- the basis MiniQuadratPuzzle_Basis.stl
- 4 large squares MiniQuadratPuzzle_Quadrat.stl
- 4 large triangles MiniQuadratPuzzle_DreieckGross.stl
- 4 small triangles MiniQuadratPuzzle_DreieckKlein.stl
- 1 mini square MiniQuadratPuzzle_QuadratKlein.stl
- 1 cover (if wanted) MiniQuadratPuzzle_Deckel.stl

All parts can be equally scaled up in size, or only in height as You like, but I wouldn't recommend to scale the size down,
