Scott® AV-2000/3000 SCBA Bayonet to Dual 40MM NATO (RD40x1/7) Adapter

thingiverse

It appears that you have provided a detailed README file for a 3D printed adapter for a Scott AV-3000 SCBA mask. Here's a summary of the contents: **Adapter Overview** The adapter is designed to connect a RD40x1/7 thread to an SCBA mask, providing a temporary solution until normal supply chains are restored. **Non-Manifold Issue** A non-manifold issue was discovered behind the dual RD40x1/7 threads due to tangency issues with typical thread creation. A workaround method was used to create threads, but this resulted in a 0.025 mm gap between the OD and ID dimensions. Future part workflows will incorporate cross-sectional cuts across major axes as part of QA to ensure non-manifold interior geometry. **Disclaimers/Risks** 1. The adapter does not feature an SCBA locking mechanism/latch, so users must continually check to ensure it tightens down. 2. Proper gaskets are required for the adapter to function correctly. 3. A negative pressure test should be performed to ensure proper fit and seal. 4. The 3D printed adapter is only a temporary solution and should not be used as a permanent fix. **Dev. Notes** * Initial model release on April 20, 2020 * Gen. 2 revisions added on May 13, 2020, including exhalation port, sub-assemblies, and gaskets to improve breathing comfort **Credits** The adapter design is based on a DIY filter assembly created by rjcroghan, and feedback and design suggestions were provided by Jack Pirone. Please note that this README file appears to be written in a formal tone, likely intended for a professional or academic audience.
