This is a really easy, fun project to dress up an old Rubik’s Cube for display, or to really hone your skills as a Rubik’s solver. Gtig posted this Blind Man’s Metal Rubik’s Cube he made with a regular Rubik’s Cube, some epoxy, and a few metal squares he pried off an old chair. There are step-by-step instructions in his post on Instructables.
In addition to looking awesome, it adds a new element to solving Rubik’s Cubes, and Gtig claims that by solving this one blind, it has made it easier for him to solve a normal Rubik’s Cube!
