Triple rubik's cube stand

I've been looking for a nice way to store my Rubik's and twisty puzzle collection but getting those simple pyramid type stands for like 20 puzzles can get quite expensive and is boring right?
So here comes 3D printing to help once again, after thinking about some ways I could store them and playing with some designs I came up with this minimalistic cube stand that can hold 3 puzzles of any kind,shape, weight and size.

The basic ''tri tower'' file provided will securely store 3 cubic puzzles
