Single DAR filter adaptor for Decathlon Subea Easybreath 500 mask. https://www.decathlon.com/products/surface-snorkeling-mask-easybreath-500-148873 For Twin DAR filter adaptor look here: https://www.thingiverse.com/thing:4289127 For old mask (not 500) look here: https://www.thingiverse.com/thing:4292778 The new mask has a significantly larger connector than the previous one. The filter cones are designed according to ISO 5356-1:2015 standard, with FDM 3D printing technology in mind. This version requires no support at all, as the locking tab is separated and can be printed flat. This makes it very strong. Easy to assemble - just click in. Once assembled, it's hard to disassemble. The initial idea comes from https://www.thingiverse.com/thing:4248511 Print parameters: - Material - PET-G - Nozzle max 0.4mm - Layer max 0.2mm - Perimeters - <=3 - Top/bottom layers - 3 - Infill density - 40% - Infill pattern - Concentric or Grid - Seam position - Random - Solid Infill Threshold Area - 70mm2 Best results can be achieved with adaptive printing parameters set. Print parameters adjusted for different adaptor areas. For details, ask in comments. For massive production, print separately adaptors and tabs. Files in project: - Subea_EB500_1xDAR_Adapter_separate_tab_v1.0.stl - full set containing all adaptor elements - ready to print - Subea_EB500_1xDAR_Adapter_separate_tab_v1.0-A.stl - adaptor with peel-off integrated support - useful for arranging multiple adaptors on print bed - Subea_EB500_1xDAR_Adapter_separate_tab_v1.0-A-no_int_supp.stl - pure adaptor - should be printed with support generated in the slicer. Be careful to place support only under exhale plugs. Otherwise, support leftovers will block the adapter from proper installation on the mask. - Subea_EB500_1xDAR_Adapter_separate_tab_v1.0-T.stl - separate locking tab - useful for arranging multiple tabs on print bed - Subea_EB500_1xDAR_Adapter_separate_tab_v1.0-W.stl - separate front valve washer - useful for arranging multiple washers on print bed. Washer should be fixed with CA glue under front valve membrane to provide initial pretension of valve. Project is continuously improved in close cooperation with Warsaw University of Technology Faculty of Automotive and Construction Machinery Engineering. Print and use at your own responsibility.
