curved edge ball and cube(tutorial) Like

by: Damian Follow

Moon Ball

The tutorial is for the subunit of the cube, but the principle is the same for the icosahedron; the triangular central element is replaced by a square or pentagon as required to provide four or five spokes.
See "Sphere of Curved Struts" for detail on how to make the curved struts

Strutty Ball

see the video on how to make the smallest one (with a 3ring in the centre). The subunit has polarity, but can be joined upside down and interlaced as well as the way shown. Each is shown unfolded and then folded (below). The extra ring on one of the spokes has the same number of spheres as the centre ring.

Here are two sorts of curved struts (one sort (bottom left) is used in "large icosohedron" shown below). They are shown in the flat state and the folded up curved state. To the left is an example of one way to join them up with the other subunit.
The curved strut on the top has a tighter curvature.
see also "Sphere of Curved Struts" for detail on how to make the curved struts

Large icosahedron

This is actually a cube, albeit with curved sides.

    Beautiful photography and creations! The moon ball is my favorite.

    They are all worthy of their own posts btw :)

    That is such a sick subunit.

    remember that it is just the one sub-unit shown, the one with the 3ring at the centre. You can also use 4rings or larger. I should put a a photo of that up
