Shower thoughts

my shower lacks some horizontal space to store soap bars, shampoo bottles and so on.
i'd like to avoid drilling the walls, so i'll try to clip struts between the wall and the shower pipe, and use this as a base for some kind of shelves.
still not sure how this will end up, but here is the first part : the awesomely parametric clipable strut.
**Note**
for some reason, the customizer hates this design. it's a shame, as about every bit of it is parametric :(
just download it and give it a try in OpenScad to get a grasp.
