Hello.

I plan to resticker my Rex Cube (original thread here). But nowhere can find correct stickers template. So I decided to dray it by myself.

The question is next: what`s exact radius of faces arcs? It`s not of Cube edge length, right?

I suppose that imaginary sphere redius rotation pass trough geometrical center of puzzle anf three corresponded corners. (If I wrong, please correct me). In this case the raduis of faces arcs will be the next:
R = a * (3 * sqrt(3)) / 4 , where a - the Cube edge length.
So the raduis of faces arcs is about 1.3 bigger than cube edge length.

If I know the raduis of faces arcs - I can draw stickers template for Rex Cube correctly.
