The Mosquito Blaster Aspirator v2

prusaprinters

This aspirator was designed and built to gently catch resting mosquitoes and move them without harming them for testing. It has a 2 position valve to switch between suck and blow.It is a remix of my own design to accommodate 8 AA batteries for 12V blowers.It accepts 5015 blower fans of any voltage. I've found the 12 volt fans produce more suction than the 5 volt fans. The rear of some fans have a hole open to the environment and should be closed with tape for maximum suction. Use #6 x 1" wood screws to secure the fan.It will accept 1-inch 7-dram vials or using the included adapter for the clear acrylic pipes, it will accept this 12mm pipe from Amazon.  The screen material used in the adapter is standard household screening cut at 11mm or use mosquito netting with the internal screen retainer (see photo for instructions).It can accommodate a variety of battery holders. The battery compartment size is 115x31x42mm. The switch is now popped out of the battery compartment giving more room for batteries.The valve is retained with a M2 x 5mm hex socket cap screw.Supplies I equipped ours with include:12V Fan (6000RPM, 5.36CFM)8 x 1.5V AA battery holder12mm momentary push buttonMosquito netting from local fabric storePrinted Specs:Printer: Bambu Lab X1CFilament: Hatchbox Orange and White PETGInfill: 25%Layer Height: 0.2mmNozzle: 0.4mmSupports: Yes only on the main body and valveBrim: Yes on main body and adapterI included the step file for the whole model incase you need to change any of the clearances between components. Use Orca Slicer with the .3mf files. Orca slicer's “precise wall” feature is used on the pipe adapter and screen retainer to keep to the designed tolerances.I used a long thin flat blade screw driver to help remove supports inside the main body. The value should be a close fit but operate smoothly. Some sanding of the valve and main body may be necessary to achieve this.  Edit: 2/14/2024 Added internal screen retainer
