The following article is taken from the original announcement of this puzzle on TwistyPuzzles.com in 3/2014.
The Heritombo Cube is a shallower cut variant of the Helicopter Cube with straight cuts that reveals the edge centers and face centers. The name comes from a diminutive helicopter.
You may notice the edge caps don’t want to quite sit flush, but it’s just a print tolerance issue. The design is not fudged. I could sand each cap but I think I’ll just print toleranced replacement caps.
