Rua Puzzle (FTRD)

thingiverse

This puzzle is a variation of the Face-turning Rhombic Dodecahedron, or "Rua," puzzle. The puzzle was first presented by Matt Shepit in 2008. I designed this version to be printed on modern hobby 3D printers like the Prusa i3 and Ender 3 models. The puzzle is quite small, measuring 43mm along its edge and 57mm in height. Supports are necessary; however, the STL files are oriented so that the parts will require minimal post-processing. Simply snap off the support material and assemble it. Turning is decent, but lockups occur frequently. I may create a second version with a spring-loaded core and tighter tolerances. Here's what you'll need to build one: Core - 1 Heli Center - 12 Heli Edge - 24 Rua 3F Corner - 8 Rua 4F Corner - 6 Rua Face - 24 M3 x 12 SHCS - 12 Enjoy building! If you create one, please share your Make.
