ResMed CPAP tubes last a long time if properly cared for. Unfortunately the rubber connectors on the ends perish and wear out before the flexible tubes do. These are not cheap, and replacements can take a while to turn up, so this print will allow you to extend the life of your CPAP hose.
This design is a mesh cone sleeve that clips over the worn rubber connector, compressing it slightly and restoring the connector's grip on the CPAP components - typically a mask or hose swivel.
The wide end of the sleeve has a notched ring on it. When the sleeve is pushed over the rubber CPAP tube connector it will lock in to ridges at the base of said connector. Once the mask or whatever is plugged in, the sleeve is locked firmly in place by the expanding motion of the rubber connector. Compression from the sleeve in turn makes the rubber connector's fit much tighter.
I print mine in TPU with "Organic" PLA support on a Prusal XL, then remove the PLA by just crushing the print in my hand. Depending on the quality of your TPU, you might need to trim hairy bits off before use.
If your tubing has broken at the connector, there is a printable replacement here:
The design is parametric, so feel free to customise the attached OpenSCAD file to suit other models and your personal aesthetic. Nice OpenSCAD meshing algorithm in there too if you want it.
