CPAP Flow Restrictor

I had seen flow restrictors for CPAP that are supposed to ease leaks on pressure changes, these were to test that. These are an experiment to see the impact of different size flow restrictions with different numbers of holes. It's a good way to see if you think it has value. I tested using “Mask fit”. The smaller the hole, the less inrush and less leaking - but more noise. I've printed in PLA, PLA+ and PETG. You need to turn support on and tree supports work the best. If you like these, you may want to consider buying one of the commercial ones available. Because of the need to print with support you end up having a lot of holes that are be a concern for contamination.
