This is indeed the second documented try to produce a working pentagonal prism around the concept of the void cube. The first try was presented by Scott Bedard in 2009 and he even presented a 3D printed sample but he considered it as a failure.
At least this first try inspired Matthew Ray two years later to design he own version with indeed works.
