This is a remix of felixna's model with an added slot for the fan's cable as suggested by Thomas Albrecht in the comments of the original model.
The notch is measured from a Noctua Redux fan, but it should be very similar for most fans.
As in the original model, the holes are for M3 heated inserts with 4.6mm outer diameter.
Please consider sharing your make and liking the original model as well :)
