Couplings HMEF Filters EPP Decathlon Dive Mask Chinese Version + STEP

3D model description

Based on the work of fittings for diving masks found on the Internet, it was decided to make a coupling for the diving mask, commercially more accessible in the Colombian market after those handled by the brand Decathlon, which are the Chinese diving masks, so it was a work of redesign and optimization of the tolerances of the existing files, in turn perfecting the forms of the elements enabling printing without the need for supports, getting a this is totally watertight seal between the coupling printed and HMEF Filter

The couplings presented here are designed to be printed only with the option of contour lines which increases their production speed thinking in a serial production. The editable files are shared with the community to make possible the realization of future works and some improvements such as the adaptation to other type of commercial filters or homemade filters for civil use.

This work was possible thanks to the participation and collaboration of the Correlibre Foundation, the Dean's Office of the Faculty of Engineering and the Dean's Office of the Faculty of Health Sciences of the Technological University of Pereira, as well as the communities of Makers Covid Colombia and Makers Colombia.

We invite you to make donations through the platform to continue the established work and to continue supporting doctors in remote regions of Colombia.

Note: This item should be performed under strict health protocols, used only by trained personnel and disposed of or disinfected according to medical criteria. Constant replacement of HMEF filters is essential for effective personnel protection. The use of PETG material is recommended for printing.

Thanks to all the people who with their support allowed the development of this project.
