Micro Liquid Dispenser

thingiverse

Users of the 10ml oil dropper bottle appreciate the availability of blunt needle type options at DealExtreme or focus at focalecig.com or alienvapor.com that enables one-handed dispensing of liquids a drop at a time. Pressing the round plate is what's needed to dispense, pressing harder allows for more drops. A game-changer for dispensing alcohol onto swabs or swatches for cleaning small items and saving valuable time for polishing gemstones when each facet must be cleaned for inspection during the polishing process. Created with FreeCAD, a notable example was printed in PLA on an Orion Delta printer. Assembly is made easier by using gel superglue or Plastruct Weld to glue parts together if printed in PLA. A critical connection to make is gluing the round pusher plate to one side of the long pusher arm. You might also need to smooth the two cylindrical posts on the base plate slightly by filing in-between them, this ensures that the pusher arm slides against them with ease. Insertion involves guiding the bottle through the large ring and then into the small ring from the top. Users prefer to attach the dispenser to a vertical surface using foam tape for secure positioning. When inserting the bottle for the first time a few drops of liquid will leak out but this is temporary due to air pressure, occasionally users may need to place their small bowl of swabs/swatches just below the dispenser to catch stray drips. In an effort to make assembly more straightforward, Dispenser3Part.stl was added on March 26th 2018, combining the base plate and ring parts into a single print which reduces the amount of assembly required. It is recommended to use this file first unless printing the split rings proves difficult at which point users can try using the original file.
