Height-limited fan duct for MKS Gen L V1.0 Stepper cooling

I'm running a JG Aurora and want to update the stepper drivers to TMCs, which require active cooling. I bought a 60mm Fan only to find out afterwards that I only had 5.0-5.5cm clearance for it.

So I designed this part. The long neck can be placed over the stepper coolers and the fan just slides onto the 4 poles. This is NOT flow-optimized, however I believe that the raw amount of air pushed around by the fan should be sufficient to cool the steppers even with turbulences.

Notes:

The gap of the shaft is only 16mm, so you don't need support for this (bridging should work). I placed a support blocker into the shaft in cura so that only the support for the walls is generated. Saves a lot of time and hassle trying to get the support out of there :)
