Phillips Respironics SystemOne CPAP air filter guard

This fits in the Phillips Respironics SystemOne CPAP and keeps your air filters in so you can't blow them out on accident. Normally there is some foam that can help keep them in there too but my supplier has given me a variety of a supplies that don't always fit perfectly but this ensures the filters are securely in place.I suggest printing 3 at once with one 1% bigger and one that 1% smaller so you can ensure you get one with the perfect fit regardless of your printer and filament choice. Print with honeycomb down on the bed.
