mini air compressor

A small air compressor/ pump that can be made to run off of usb. it makes about 1.25psi on usb and may make more at higher voltages or with a larger motor. the motor options are a 380 or 450 motor(540 vtwin ). the first version is all plastic on metal running parts but seams to hold up decently , time will tell how well tho .

I have a few plan in mind for this as well as having them as a good backup for my aquariums and other systems requiring air pumps .

this pump moves more air than a standard small aquarium air pump , and should be suited for air assist on an engraver , or maybe as a remote cooling system .

materials:
all printed parts ( a few head options available)
6mm dia stainless straw, ( acquired from dollar store or wherever .)
8pc m3 x 6 cap screws
4pc m3 x 20 cap screws
2pc m4x4 screws
1pc m4x20 cap screw for wrist pin
5pc m4 hardware for flywheel
2pc m8 setscrews for counterweight.
