Summing Remix.\r\n\r\nThe adapter now seamlessly integrates with the 3M Raspirator. You can confidently use Scott pro2000 filters (NATO 40mm) without any issues.\r\n\r\nVersion 0.2 and above boast a simplified design, eliminating the need for supports. However, they do require precise printer calibration and frequent cleaning.\r\n\r\nAs of Version 0.4, printing has become significantly easier. The design is more forgiving and less prone to errors.\r\n\r\nIn Version 0.5, the wall thickness was carefully optimized to prevent cracking and leaking issues associated with earlier versions like 0.4.\r\n\r\nVersion 0.6 expands compatibility to include 3M 6200 filters, in addition to the previously tested 3M 6500 and 7500 series.\r\n\r\nThe Version 0.7 design is even more compact, as evident from the provided images.\r\n\r\nAfter printing your adapter, take a moment to brush its exterior with acetone. This simple step significantly enhances the plastic's airtightness.
