bladeless fan 80mm

New base for blade less fan found here. https://www.thingiverse.com/thing:2869887
Ive included two files. Both for 80mm fan of width up to 27mm. The original worked well for me but did need a little filing to get a nice snug fit. There were two very small ledges that showed up in my print so that could be the fault of my printer? So if your printer is finely tuned the original may work for you off the print bed. If not I added a millimeter of extra tolerance in the second file.
