PANDAflow - flow restrictor valve

thingiverse

Team PANDA [Zurich, Switzerland]: We introduce a **3D printed flow restrictor**, designed to integrate seamlessly into a 22 mm conical connection (anaesthetic/respiratory equipment). Please note that this is NOT a medically approved device and should not be used for medical purposes. To achieve a secure seal, an O-Ring with an ID of 35mm x D 3 mm or similar is required. Alternatively, you can use a larger O-ring and trim it to an angle; the pressure from the wall will create a tight seal as well. **PRINTING/ASSEMBLY** The tolerances of the printed pieces must match perfectly, which can be challenging due to varying printer specifications. If the parts don't fit together smoothly, scale them in Cura in the X and Y-directions only, making small adjustments each time, and keep track of your changes for future reference. To begin printing, start with the base part to ensure a secure connection to standard 22 mm connectors. Next, print the cover piece and verify that its thread matches the base. Add the O-Ring, press the two parts together, and screw the base into the cap. **MATERIAL** We utilized PLA material with a 0.4 mm nozzle for all printed parts. No support structures were necessary if the model is printed as shown in the provided image.
