5 Litre Bottle lid adapter for CPAP machine
As I use a CPAP machine, I have to constantly refill it with demineralised water everyday from a 5 litre bottle. This got tiresome fast!
So I designed this bottle lid to fit a silicon hose to go directly from the bottle to a small water pump I bought online. Now, at the touch of a button, I can pump 200ml of water without having to lift up the large bottle.
My water pump came with 12mm silicon hose. It has an Outer Diameter of 10mm and an Inner diameter of 7mm. My part is 7.3mm so this makes for a nice tight fit.
