Injection-moulded Silvana adapter for Decathlon face masks (with white connector). This allows to provide oxygen supply to patients in CPAP applications (or filtered air for healthcare workers in PAPR applications) using the Decathlon scuba mask, filtering the exhaust gases.
The original Silvana series were 3D printed (https://www.prusaprinters.org/prints/27214-silvana-decathlon-face-mask-adapters). At one point we decided to make an injection-moulded version for better sterilizability and airtightness.
The three output pipes are directly connected to the three channels of the connector, of which the central is intended as intake and the outer two channels as exhaust. The exhaust channels are not interconnected due to manufacturing limitations (injection-moulding using two mold halves without additional moving parts).
3D printable accessoires are available to convert the 22M ports to 22F or bend these outwards or shut off one of the exhausts.
It is produced in low quantities at University of Twente. You can request adapters (mail me at [email protected]) and we will ship a small batch to anywhere in the world for free.
If you are planning to produce your own mold set: contact us for details about our setup to save you some time.

Print instructions
The Silvana IM part is not intended for 3D printing. Use the regular Silvana adapters instead (https://www.prusaprinters.org/prints/27214-silvana-decathlon-face-mask-adapters).
Cap/connector/angle can be printed on any standard 3D printer and standard settings, preferably with 100% infill.
