Thats for this :) would it be possible to add a clean stl?
I am not able to get a clean conversion with openscad and most printing services want an stl file :-/

Thx in advance.

I love innovative ideas like this. I think you have an awesome idea. How about incorporating a simple one way valve and then just use the bottle itself as the pump. So you would just squeeze the bottle, release (the bottle fills up), and squeeze again... An example of a simple one way valve would be like the ones on kids sippy cups. Awesome work man... TD

Thank you for the feedback! I like the idea of a "simple one-way valve" - that would be a relatively simple addition. However, all of the things I'm using this for have their own one-way valves on the intakes. Not so sure about using the bottle as the air-supply/bellows - the advantage of the plastic bag is low-weight + massive volume. Would be interesting to compare, though...
