Blower Fan holder for 2040 extrusion

Since Ender3 electronics fan is tied to the part cooling fan, this is an attachment to blow air into the electronics compartment to cool down the drivers with a blower fan.
This needs M5 T-nuts and bolts to hold it in place.

I just used a blower fan that works with 12V input, so I added leads to the PSU for it.

With the previous version, I used 35% infill, and broke the top portion while trying to drill out the holes. It still works, but I made the holes bigger to fit M5 T-nut & bolt.
