[8/6/20 V2 hinge pin uploaded - now contoured and sized to sit flush against the main body for a much nicer look.

I did design a variant that had a much less bulky body, but it ended up using practically the same amount of filament due to the amount of support material needed].

A simple application of a lever to make pushing the pump easier.

Perfect to folk with weaker wrists, arthritis, larger tools etc.

Functioning base designed for a bottle with a 27mm diameter neck, and a 30mm diameter lid. You may need to shave the inner ring a little to adjust to fit perfectly (it's a tight fit!)

Works best if the bottle has quite a wide base to prevent it from toppling. Results may vary with different bottle shapes/sizes!

The design should scale up without an issue but may need a little rework if scaling down, due to clearance tolerances being designed for this sized print.

Included is also a base without a hole in the bottom. Will accommodate any diameter lid up to 30mm - all you need to do is add a hole in the centre of the recess to accommodate the diameter of bottleneck you need.

Prints without supports, however, you may want to enable supports just to help out the curve around the hinge area get started.
