MPSM Extruder box with Fan

I added a higher torque nema 17 motor with my smoothieboard conversion and found the motor got a bit warm so I added in a fan mount to cool the motor down.

Usually this is due to too much amperage but even when I lowered the amperage below what the motor is rated for in the config file it still got a bit too warm for me.

Infill is up to you, 25% or better is probably good enough.

I used a 40 x 20mm fan.
