ResMed AirSense10 CPAP Mask/Hose Connector

thingiverse

My friend relies on a ResMed AirSense10 CPAP machine for better breathing, but he's encountered a frustrating issue - the small connector that links the hose to the mask is prone to stress cracks due to its slender design and can only be obtained as part of the entire hose assembly kit. He wondered if I could craft a replacement for him, so I used Fusion 360 to create one. According to his instructions, the inner diameter should connect to the mask while the outer diameter connects to the hose. Since it didn't require an exact replica of the original, I opted for simplicity and was pleased that he found it effective! A picture of the OEM original is attached, clearly showing how thin this part is and how easily it breaks. The flared end attaches to the hose, so I made sure it's thick enough - the flare isn't crucial in this design.
