Bottle Stand (Dryer)

I've seen many designs of bottle stands, but a lot seems overly complicated. Furthermore, I want it to be printed flat to allow strength where it matters (if you print designs standing they easily break horisontally, which is exacltly what you want to avoid in a bottle holder). Printing flat also means it's a very easy design to print successfully. I've designed it with toleranses that works well on my printer; but if there are problems, just increase the or decrease the size of the bottom part a little)

Simple modular bottle stand. Combine cottom and tops as you want. The design is made for bottles with a diameter of 80 mm.

In the image we see:
X1 x X1 (purple)
X3 x X2 (green)

By default you can easily get any combination of
{X1, X2, X3} x {X1, X2, X3}
