This is a 3D printable air-jet for making microdroplets using an air-source. It can be glued to adjustable supports or directly attached to a syringe pump.

# Print Settings:
Printer: Monoprice Mini v2
Rafts: Does not matter except for the adjustable screw and support columns. These should be printed with a raft or brim to prevent disconnection from the printing platform due to their height and benefiting from being printed upright.
Supports: Not necessary. If bridging is a concern, supports can be used.
Resolution: 0.0875 (A value specific for Monoprice Mini printers)
Infill: 20%
Material: Hatchbox PLA 1.75mm (White)
Extruder Temperature: 190 C
Platform Temperature: 60 C

# Post-Printing: Ensure no blockage within the air outlet. If supports were used, remove any supports inside the air-jet with needle-nose tweezers. Attach the air inlet nozzle and seal if desired. Attach to supports as necessary.

# Design notes:

This model was designed using Fusion 360 (Autodesk). The air-jet was designed to allowing a needle to be inserted into a path of airflow such that the air flows towards the outlet shared by the needle. The air nozzle was designed separately to create a large opening to benefit cleaning and to adjust the direction of the air nozzle. We designed the perpendicular columns that flank the air-jet to attach the device directly to the syringe pump or be glued to support adjustable legs. The files for these support legs are also attached.

A support leg is 4 distinct parts composed of the base, which supports the two support cylinders; a screw, for adjusting the height; the support cylinders, which flank the adjustable screw; and an elongated nut piece, which attaches to the support cylinders the screw.  We attached the elongated nut to the air-jet columns with glue. Additionally, support cylinders were glued to the base to keep them in place. Additional post-printing processing may be required if the support cylinders are too thick to fit into the holes of the base part.
