According tomedia CNET, the new crown epidemic forces people to wear masks on hot days, but wearing masks for long periods of time can be uncomfortable. A cloth mask with straps takes longer to wear and needs to be tightly tied. The face coverings such as headscarves and scarves cover large areas, but are not tight and can easily slip. CNET reporter Dan Ackerman has discovered something that makes it easy to wear and remove a mask, but also securely secures it.
Ackerman launched a 3D design program in which the easy-to-use (and free) browser-based Tinkercad and began designing a set of mask clips. One of Ackerman’s 3D printing techniques is to combine 3D-printed parts with magnets to create a more useful design, so he designed a set of mask clips that don’t need to tie anything or bolt plastic clips together. Instead, he designed the clips to be safely sucked together using small magnets.
Because Ackerman printed and tested different designs, he made the magnet holes deeper, so it was flush with plastic and expanded to make it easier to adjust. There is only one STL file (3D printing software file format) – print two copies, and they should be perfectly combined.
In this case, Ackerman uses a magnet with a diameter of 8 mm and a depth of 3 mm. If people want to use different sizes of magnets, they can adjust the design in Ackerman’s Tinkercad file. Depending on your filament and printer, the magnet should fit in the clip, but Ackerman uses some super glue to permanently connect it.
