Holder for cooling a NEMA 17 stepper motor I use this to cool the Z axis of my 3018 cnc mill. The fan has the size 40x40mm, hole spacing 32mm Of course, a flatter fan can be used, mine has a height of 20mm. Only had this in the drawer :-) The housing sits more or less firmly on the NEMA 17 since there are different designs. Have a NEMA since the housing sits tightly, the other loose. Test it.
