CPAPpollo (you know CPAP~Apollo..... ) or headphones for Apollo

If you don't know what a CPAP setup is like, just think of it as remote powerful fan, with air traveling through the CPAP tube. Usually two goals in mind with such setup, more air (definitely the case), and lighter toolhead compare to onboard fans (not the case here, weight is about equivalent, but doesn't really matter, it's a fun funky project anyway )

The apollo was never designed with CPAP in mind, but still made it happen, so this is a fun yet functional add-on to the Apollo, and turns it into a CPAP setup for mind-blowing part cooling.
There will be definitely much higher airflow than any normal 5015 can deliver.

you will need a CPAP fan (something I have never used, check Mellow and BTT offerings, as they have parts or kits), which is basically a powerful fan with a round opening to go onto the CPAP tube

Go on discord if you have any questions, as one brave patron (PrinterMcgee— thanks!) printed it and put it together, with some quick airflow test, you can check out his video on YouTube 

Parts to print:

• UltraFan main body that you'll find in the respective apollo zip, that model is present in most hotend zip, if your hotend doesn't have it and you want to try it let me know.
  difference is that it has a much wider duct opening

• Ultra fan ducts found on this post

• current backplate are compatible with it. (for that reason the right side has both side screw closer to the front, and rear one remains unpopulated)

• the "headphones", file here

• cpap_adapter_XXmm_opening: rule of thumb, measure the rubberized opening of the tube end, and select a size above from what you measured

This doesn't need to be incredibly strong, so you can go lighter, with less wall and low infill.
No print support needed,

you will need a couple heat inserts, and m3x6 screws.
Side screws should preferably be M3x18, but the more common M3x20 will be totally fine.
