Bottle holder for Ikea Svärta loft bed

Clips on to the railing rather tightly. 

I've printed it both with and without supports (build plate only), on it's side. Turned out good enough, bit rougher without supports, as shown in the photo (before cleaning up rest of the stringing.) You might want to tweak it a bit in slicer for cleaner results.

Fits 73mm diameter bottle.
