This was a quick and dirty Tinkercad hack to adapt AntonioJose81's cool fabrikator mini fan stand legs to use on my Asus RT AC3200 Router which runs a little hot. By no means a perfect fit, but will get the job done until I can come up with a better fitting design

You will need a 140cm PC fan, some case fan screws or nuts & bolts for the fan, and a USB fan adapter to complete this (available on ebay, or you could wire your own somehow). Assembly is pretty self explanatory.

The parts did throw up some manifold errors here and there for whatever reason, but seemed to print fine for me otherwise.

There's also a chance the Asus 87u and 88u chassis may also be compatible with this stand being of similar size - although from the pictures I've seen there are some significant differences to the underside.

To complete you will need to print one piece each of parts 1 to 4 which are also labelled with their respective corners.

When attaching the fan you are supposed to use a nut and bolt of some size that was used on the original design I remixed from (I'm not sure which), but I've also included another set of files marked "CFS" which are altered to better use short PC case fan screws, as I found when using those on the original design they threaded and came loose easily.

The "CFS" labelled parts simply do away with the nut recess and have a tighter thread hole so the case fan screws can grab better. Assuming the more infill used here the better they will grip. Used around 25% infill myself and seemed to hold okay.

To use case fan screws you will of course need to find a Phillips head screwdriver that can fit through the top screw holes of the case fan, or at least one that is not too big that it can't be used to ream and forcefully widen the holes slightly.
