80mm fan bracket/holder

This is a simple design to mount three 80mm computer fans together. If you want to mount more (multiplicity of three) just print more and join them with the part from "fan bracket.stl". I recommend using two brackets to join two fan holders (one top, one bottom).
Useful for all cooling purposes no matter if for a PC or providing yourself some air flow during summer.

There is also a fan holder that comes with the fan grill all in one.

You can save with the infill material but that might weaken the whole thing. You can also try to scale the z-direction (thickness) up to get a more rigid structure. Experimenting is on you and your needs ;-)

Mount fan and fan bracket with M4 screws and nuts.

UPDATE to v1.1: Tuned export settings, so rund structures remain round and not "polygonal"...
