120 blower CPAP adapter

I had a 120mm blower and I wanted to try CPAP, so I made this.This is for those who have the fan and want to quickly make a basic CPAP setup, if you don't have the fan, get a ws7040 instead.I tested this in a video here: The compact version is not tested, let me know if you test it.There's no specific mounting points, that's up to you.STEP is included.
