Being lucky to have a classmate who is expert about 3d printing is definitely a opportunity to take advantage of and make test to develop my study about possible object composed by polyhedra. This time in particular I wanted to start 3d printing tetrahedrons, composing an object I already studied the mechanism but making it with other material and tools.
Understanding and then being able to design a shape with a different new tool permits to develop new skills and see a project with a different mindset. I was able to avoid most of the errors because I had a person as tutor who could explain me what should I do in order to get a precise shape. These subtracted and decrease the number of possible mistakes I would have done, but there are still the ones I need to discover once I try to assemble the tetrahedrons.
First of all I will verify if they compose a new solid which doesn't get any empty space, so where all the faces of one tetrahedron touch the ones of the other, making a icosahedron. After, I will glue the little hinges I got and remake the folding-unfolding icosahedron (the blue one I did last year). So that for the next 3d printing I would know the dimensions to leave for the hinges in a way they are embedded in the tetrahedrons.
