Colored by hand with magic markers.
A smaller version of Five Intersecting Tetrahedra without an icosahedron inside. There is just enough space between the pieces that it will print as 5 separate objects. The edge length of the tetrahedron is 5cm, it stands 5.7 cm high. Without the inner icosa, this version will allow more movement of the pieces. I have also rounded the tetrahedra corners so they aren't so sharp.
The photos show the model printed in white and colored by hand using fine point felt-tipped pens. I inserted small pieces of paper to protect the other pieces while coloring one, I was somewhat successful. I was able to color each piece completely on the outside, but I didn't try to color the insides as you can see in the photos.
