Has anyone found a good layer fan that can be printed and attached to a stock 2020?
Most of the ones i see have additional mounts or hook up to parts of different extruders or hotends., im not sure what the model is with the folgertech but i know its not bowden or a v6 hotend lol.
my pla prints sag on bridges, i read somewhere a layer fan should fix it.

Mk7/8/9 is the type. I run e3d so I can't be much help for fans. They should be plentyful on thingiverse.

For over a year printing PLA only on stock 2020, I've gotten dynamite results with this one:

Positive(s): this fan duct is super simple to print and install. Only parts required is replacing the two fan mounting bolts with slightly longer ones. No need to buy additional fan, or deal with additional wiring. Cheap solution! Couldn't be easier.

Negative: not good if you are looking to print other plastics like ABS -- no direct way to independently control and avoid blowing cool air on plastic being printed (other than physically blocking the lower duct -- i.e. with tape).

Another issue with not being able to control it is that you actually don't want it blowing on the first few layers which could cause issues.

I have seen some on www.thingiverse.com that i would to try but not sure how to wire it up and at what point to turn it on.
I would like to find this on https://www.youtube.com/watch?v=hRE5USuJUg8

The only way that I know of to do it is to use an add-on board for the ramps. I would suggest upgrading to an all-in-one board to simplify it. You will also get better components. A lower end suggestion would be the MKS Gen and would give you the direct fan control terminals.
