Pico Fan Mount for BI v2.5

This is a crude fan mount and duct for a Boots Industries v2.5 printer. It's my first pass to get things running and will be refined when I get the time. (Note the fancy paper top I added to the duct so I didn't have to design around the features that were in the way...)

I just used 18mm 3mm screws to assemble. They were too long but it's what I had handy.
