Another polyhedra construction set 20 mm

Here is another clipped shape game to make polyhedra.
There are a lot of them on Thingiverse.
But there was not mine yet: D

The ridges are 20mm, which makes it possible to make shapes of reasonable size and printing time.
On the other hand, small parts become difficult to detach when they have several connection points.
This is particularly the case with triangles.

I add, plates that can clip over, and make the shapes smoother, or drawn on it, for example, a personalized die.

Impression :
I printed in 0.2, it is sufficient, so that the clip is done correctly.
Without support of course.
