Dropper & Bottle

thingiverse

This was an experiment mostly to see if it is possible to print a flexible chamber (the dropper bulb) in something other than flexible TPU filament - I printed this in PLA. It actually works pretty well as a dropper, although getting the dropper and bottle to print water-tight is a bit of a challenge. The dropper has an integral tapered stopper which fits nicely into the little bottle. And the bottom of the bottle is tapered so that you can easily suck up the last drop. This dropper is probably fine for water, alcohol or light oil. *Do not* use it for your eyes - who know's what's in your filament?
