I assume all cubes come standard with two ripple hooks in the front, and none in the back [only empty holes].
I had enough holes, and bungee's to do me for the front, so I moved the two hooks to the back. The back doors look more like they finished going through the assembly line now. As for the big keyhole shaped holes that were left in the front, I found some 1.5 inch sticky backed mirrors [$2 a pair], and they fit in the void just perfect. If I think of something later on to use the holes, or the ripple hooks for, then they should be easy enough to pull off.
I'm including a couple of pics to show what it looks like. If you use your imagination, they look like sight glasses, or even camera lenses. Either way it still looks better than empty holes.
By the way, I am a machinist. I work with mechanical, and electrical engineers. If anyone has any idea's, let me know, and I will see what I can do. Those ripple hook holes have endless possibilities. ;D
