Note the 4-6-2020 update is a 50 mm longer. So now you have two sizes to choose from, This is a remix of crealty face mask buckle. This version is for TPU filament. The original only provided the STL file. I am providing the autodesk.123dx file if you wish to customize. The original did not print well on my 3D printer with TPU, so I added about 1 mm of thickness to the unit so it will print nicely.and recreated in autodesk 123, I think the original was designed to be printed with pla or abs as a disposable unit, but I wanted this for a reusable mask at home. This can be easily sterilized with a spray bottle and 70% isopropanol. Do not spray near a flame! https://www.thingiverse.com/thing:4187448 Update -4-6-2020. After I printed about 30 of these I tried to use one and discovered, that the original design (from Japan) was made for someone with a much smaller head then I have, so I made another version called comfort buckle which is 50 mm longer. This may be a little large for some, but you can always snip off the excess and make it fit the users head size. Also not that the new comport buckle is made to be printed from ABS Not TPU, comfort buckly is based on the same thickness dimensions as Creality but is 50 mm longer.
