Jet nozzle for generic Aliexpress Turbofans

I purchased a generic turbofan off Aliexpress to blow to dust out my PC, laptop, cameras and so on, but noticed that there were no ready-designed compatible nozzles for my particular variant. Hence, I went the extra mile and tried to fit in a turbojet design inside the narrowed replacement nozzle:

The turbofan that I got has 8 straight spokes and is about 35mm wide:

You can print this out of anything that you want, I used some generic black matte PLA. If you do not want to use the presliced profile, pay attention to your bridging. 

Due to a bug in Bambu/OrcaSlicer, you must use at most 2 walls, else bridging will be done mid-air. This might have already been fixed with PrusaSlicer, so ymmv.

I designed the part for what magnets I had around, which were 13mm x 2mm ones, but smaller diameter ones should also work fine (10-12mm) as long as they are up to 3mm in thickness. 

I recommend using hotglue to stick the magnet to the part, as that still allows you to remove the magnet afterwards by just heating it up with the tip of your hotglue gun if you stick it the wrong way around.
