This is a simple adapter to connect a 40mm blower fan to a 40mm female pipe fitting. In the photo it's shown inserted into a UK standard 40mm push fit plumbing pipe. Easy to print without supports.
The external diameter of the male circular fitting is 40mm, and the length is 9mm. Overall length including the fan is 50mm. There are three mounting holes suitable for M3 screws.
I'm using this for a Halloween low lying fog effect, with ultrasonic mist makers...
