Shampoo bottle pump top

This is inspired by this: https://www.thingiverse.com/thing:3416752

I include 2 versions: a printable version, and a normal version.

NOTICE: The printable version is designed so that the base of the vertical cylinders has a floor, so that the first layer ring won't print on air. It is designed for 0.2 mm layer height. This will give 1 layer of bridging before starting the cylinders. This floor can be removed with a pencil or drill etc.

This is designed for a 12.3 mm shaft pump.
