Description

if your collection does not have this - it's a great chance to get a wonderful puzzle !!!

Description of the author:
The geometry of this puzzle is a strange one. At first, I tried creating a puzzle based on the geometry of the triangular orthobicupola, but doing so results in a multiple origin puzzle. I wanted a shape where the dihedral angle between two rectangles or between a rectangle and an equilateral triangle was 120°, as this allows edge pieces to be exchanged freely between these faces. The result is the shape you see here. One interesting property of this shape is that the length to width ratio of the rectangles is equal to the square root of 3, and the height of the puzzle is the same as the longer edge length of the rectangles.
I originally wanted to make this puzzle deeper cut than this, but I could not find a good way to do so without creating lots of tiny pieces, so I opted for these curvy cuts instead. As you can see in the pictures below, this puzzle jumbles, so I decided do a bit of unbandaging, which makes the rectangular faces appear symmetrical.
Those wondering where the name comes from: one other name for the triangular orthobicupola is the anticuboctahedron, since the shape is like a cuboctahedron that has been cut in half, rotated, and put back together. The rainbow cube is probably the best known cuboctahedron-shaped puzzle, but I also thought that this name was appropriate because the two puzzles otherwise have very little in common, but are both 14-sided.

The stickers have been cut and applied very nicely, and the puzzle looks and turns great.

My only complaint is that I scrambled it a couple of weeks ago and still have made zero progress in solving it.. I forgot I suck at bandaged puzzles :D

I think it's better than you could expect from a printed puzzle. Perfect turning, perfect stickers, polished surfaces. Maybe a bit too big, but the shape makes it comfortable to play with.

My first 3d printed puzzle from grigorusha, excellent build quality, and looks great in pink :D.

Deceptively tough puzzle, my solve method is currently way too complicated, hopefully I'll find a way to streamline it..
