SK: Bol som osloveny ci by som nakreslil k mojmu krytu prachoveho filtra 3M ktory sa nachadza tu: https://www.thingiverse.com/thing:3982639 adapter na prachovy filter. Tak som ho pre Vas ktori mate 3M tvarovu polomasku nakreslil. Upozornujem, ze pri dobre nakalibrovanej tlaciarni bude pasovat docela pekne, ale nemusi pasovat na originalny kryt prachoveho filtra ktory je vylisovany od firmy 3M. Aby som pravdu napisal, ich kryt prachoveho filtra nepasuje na ich uhlikovy filter!!! A ich prachove filtre pasuju lepsie v mojich modeloch ako v ich originaloch. :-)
Adapter je optimalizovany na prusa-slicer. Podpora je nutna. Tlacil som ho z PLA plastu.
02.04.2020 - Dovolil som si model oznacit svojim cislom pod ktorym sa da najst na thingiverse cez google.
Komu sa pokazilo na 3M polomaske upínanie remienkov moze si tu stiahnut nahradný diel. https://www.thingiverse.com/thing:4252159

I was invited to draw my 3M dust filter, which can be found here: https://www.thingiverse.com/thing:3982639 dust filter adapter. Take it as a member of your 3M face mask. I guess that with a well calibrated printer will fit pretty nicely, but can not fit on the original dust filter cover which is molded from 3M. To be honest, their dust filter cover doesn't fit on their carbon filter !!! Is dust filters fit better in my models than in their originals. :-)
The adapter is optimized for prusa-slicer. Support is required. I pushed it out of PLA plastic.
02.04.2020 - I dared to mark the model with my number under which you can find on thingiverse via google.
