OpenSCAD - Ender KE or Ender SE Super SImple part cooling fan/fans mounts

I have found over many years of using the various 3D printers that I own, that being able to see the nozzle, especially when laying down the first layer, is important.  You could always cut away the fronts of the stock Creality fan shrouds, but I always like to be able to return my printers to looking stock, in case I sell one of them.

I tried to buy new replacement fan shrouds from Creality, that I could cut away the front but Creality said they are not available.  Looking at the many fan shrouds there are to print, they all suffered, IMHO, from two problems; Long print times, and the need for lots of supports.

These are about a simple as they can be made, and do NOT require any supports.  Even the air ducts will print reasonably well without supports, only requiring a bit of clean up in the outlet duct area, with a sharp hobby knife.  They use the original 4010 blower fans, with no additional wiring length needed.

You will need M2 screws, washer, and nuts to attach the fans, and M3 screws, and washer,  to attach the mount to the side of the extruder stepper motor.  For each fan, you will need 2 each, M2x16, and M2x8.  For the stepper screws, 4 each M3x8, or M3x10, depending on the depth of the holes in your stepper motor. For the left mount on the Ender KE, you will need M3x14 screws and washers.  I keep kits of screws of various sizes and lengths, so don't pay much attention to designing for specific hardware on hand.

Note on the left side view for the Ender KE, you see the Orange thumb grab bar at the top of the extruder gearbox assembly.  It is held in place, using M3 screws, into unused holes in the side of the gearbox.

The fan duct that attaches to the 4010 blower fans comes from here, with my many mods:
