upside down bottle holder

This is a simple solution for an old problem.

I was tired of waiting for the hair gel to flow to spout when I turned the bottle over. This device holds the bottle upside down so the gel is always ready to dispense immediately.

This would also work well for shampoo bottles that are nearly empty.

The holder is sized for a 28.5 mm diameter hole that is about 25 mm long. This gave the 27.5 mm cap, 1 mm clearance on the diameter.

For other hole sizes simply scale the .stl by the following ratio:

ratio = (new hole diameter)/(28mm)
