I present Mohammad Badir (aka Proxy-Pie) puzzle - Master Rua
with the permission of Mohammad Badir from his drawings I made the Master Rua. this is a very interesting and rare puzzle.
if your collection does not have this - it's a great chance to get a wonderful puzzle !!!

From the designer:
I'm presenting my biggest puzzle yet, the Master Rua! It's a Face Turning Rhombic Dodecahedron (or FTRD for short) that turns on multiple layers. It's effectively a slot filler in the FTRD series, where the Rua has 2 pieces to an edge, a standard FTRD has 3 pieces to an edge, and the Master FTRD has 5 pieces to an edge, this puzzle, of course, has 4 pieces to an edge.
It joins the relatively sparse list of multi-layer jumbling puzzles. Here's where it gets interesting though. When you make turns on the top, or both the top and 2nd layer, the puzzles jumbles as you'd expect. However, when I attempted "Slice-Only" jumbling, I ran into this interesting case.
I didn't expect to see this. Apparently, the edge rhombus piece, and some of the rhombus centers are mechanically equivalent! This means that the pictured state isn't jumbled on the mechanism level, but some moves still block due to external overhead bandaging. I find this extremely interesting. I didn't notice it while designing the puzzle, nor while I did the test assembly. Keep in mind that this move isn't possible on the virtual version in the pCubes simulator.

As for the proportions, the outer layers are twice as thick as the inner layers, so during a regular FTRD scramble, the grouped center pieces would be the same size as the corners and some other pieces. It's this aesthetic that pushed me to make this puzzle in the first place, since I wanted to play with and solve both the Rua and the regular FTRD, and this puzzle allows me to do just that.
