CPAP Supply Adapter - 8mm Hose

This is untested at the time of posting, however the fit to both the hose and enclosure are great. I printed in PETG. High strength to allow for clamping on the hose - just don't go wild on it. You can use a small hose clamp, or zip tie. Depending on your setup, you may choose to reduce the length, but I retained that part of the design.

I changed the adapter to allow for Silicone hoses which are 8mm, and more flexible than the standard 15mm CPAP hoses. I added an internal 0.4mm shelf to eliminate the need for supports. You just need to break through this before you use it.
