Replicator Dual Fan Mount
by aubenc, published
Designed for a 40mm fan (the opening is 40.4mm side to side). The long plates (bottom and back) are 1.5mm thick the thickness for other ones (fan casing) is 1.2mm.
Unfortunatelly, the walls are thin and their thickness is not parametric, they can break easyly: "todo" list.
I'm using a taped piece of cardboard to close the thing: "todo" list.
The air exit is big, far from where is supposed to be and it is not ducted, that can have some negative impact: "todo" list.
And so on, and so on, and so on... for the "todo" list, don't be surprise if there's no much progress in the work for a while, I may even just uncheck the WIP flag and let it like this :-(
I managed to break it so I have add some reinforcement. Also added a couple of little tabs to center the thing and a sort of clip to keep it in place without the need of using tape*.
(*) Tape is still needed for the cardboard AND I think it's a good idea to use some to secure it, this time I have placed two little pads of thin double-sided tape.
The STL (v02) differs from the (green) one in the picture (hope it's fine).

Cooling the material that has been lay down. Usually you don't want to do so however, sometimes this will improve quality.
One example is the part in the picture, sliced at 0.1mm layer height, the overhang is close to 75 degrees. Both where printed with the same gCode and using PLA as material.
The yellow one (build cancelled mid print) is showing a lot of big issues where the PLA is lay down "in the air". The issues are also present in the orange part, however, in that part these issues are negligible.

I printed mine with quite a low infill and is way too fragile! If there's a "next time" I'll give it a nice 50% or more.
I'm using an external DC power supply because the fan I had is rated for 12V, I have no idea if the "EXTRA" connections in the Migthyboard can be used and/or if the M106/M107 would work. May be somebody can post a comment (?) That would be nice ;-)
