centrifuge blower/fan with output hose connector

this is a 3d printed blower / fan, literally a small centrifuge pump
this is a variation to centrifuge blower/fan
with a hose connector for a 10mm diameter hose
you could use one of those corrugated tubes / hoses (e.g. from amazon,  ebay ) or ordinary 10mm internal diameter tubes (slighly smaller internal diameter 9mm may fit)

this blower is ideal as a cooling fan e.g. for a raspberry pi with heat sink or it can be used as a general centrifuge fan / blower perhaps for cnc to blow away dust / cooling etc

this blower is sized for the common low cost '130 dc motors' (not included)

but the motor mount is part of this print

note however this is a small motor and hence it is unlikely to deliver high output head (pressure). However, the flow rate could possibly be decent for low head (pressure) use.
the mount holes for the motor mount is 26mm apart so you could possibly substitute a different motor, but it likely wouldn't fit the motor mount designed for '130 dc motors'

the mount holes 1.8mm are sized for a m2.5 (2mm hole diameter, 2.5mm thread tiameter) wood / self driving screws (not included, but are readily available on ebay, amazon etc)  to make easy assembly. a screw of 6mm or 8mm length should be adequate to fasten the parts together. this design using screws also allow you to open the case in case you want to clean the 'fan'/impeller etc
the impeller is sized for a friction fit to the motor with shaft 2mm diameter.
the width and length (the main 'fan'/centrifuge pump part) is about 5cm x 5cm and about 16mm thick excluding the motor and motor mount
