I just ordered a 12v 50x50mm blower and am going to try to test print this and fit it on the front of the direct drive mk8 extruder that came with the acrylic kit.

I also have a 40mm 12v fan already as a backup to the coldend fan that I might try and mount on the other side. not sure what mount to use for that or if the mount I'm printing for the blower is the best. Any input would be welcome.
