Dust filter cover for 3M mask

thingiverse

I bought a 3M protective mask with carbon and dust filters. When I put on the original dust filter cover, it cracked because it was made very tight and was made of thin plastic. I didn't find any functional replacement on thingiverse, so I decided to draw this cover and publish it. I drew the cover to print from both sides. The model is optimized for PrusaSlicer where the walls at the nozzle are 0.4 mm thick 4 perimeters. Support is of course necessary when printing from both sides. Any material can be used. I tried PLA and PETG. The model is relatively accurate and should be slightly stiff on the carbon filter when the printer is set up correctly. On the original cover are 6 pieces of teeth for a firm attachment to the filter. I left only one tooth on the cover, which is rich enough. Of course, in the coronavirus pandemic, I drew another dust filter cover, taking care not to use the printing support and the resulting product being printed as soon as possible. There I have already made two clicks because the cover is lower and has less rigidity. Both products are numbered to make it easier to find them on Google. After consulting a user who is pushing these covers for doctors in Slovakia, I modified the original "kryt na filter hexa 05.stl" and made it 2 mm deeper, "kryt na filter hexa 06.stl" because doctors do not have the original original dust filters from 3M, but they manually cut a replacement from another material and put more layers there. I also added two more teeth to click from the side. It can also be used with the 3M 603 FILTER ADAPTER which I also drew and can be found here: https://www.thingiverse.com/thing:4215903 I added a new product, a series of half mask filters https://www.thingiverse.com/thing:4159038 Those who have gone wrong with the 3M half-mask clamp can download a spare part here. https://www.thingiverse.com/thing:4252159
