Soviet GP5 filter short printing time

I decided to cut the original GP5 filter because the printing time and the pla used were too high. Support required only for the base.
I suggest do not paint the thread of the filter because will be hidden inside the mask and will not release color to the mask-thread.
Thread: 40mm GOST (doesnt work with NATO gas masks)
Enjoy your mask with an asbestos-free filter!! :)

P.S.: Thank you very much to the owner of the original 3D model ! (bluepugpoo)
