Dropper & Bottle

thingiverse

This was a test to see if it's feasible to print a flexible chamber (the dropper bulb) with something other than flexible TPU filament - I printed this in PLA. It actually performs well as a dropper, although getting the dropper and bottle to seal water-tight is a bit tricky. The dropper has an integrated tapered stopper which fits neatly into the little bottle. And the bottom of the bottle is tapered so that you can easily suck up the last drop. This dropper should be fine for water, alcohol or light oil. Don't use it near your eyes - who knows what's in your filament?
