In the Zadlaščica mountain gorge, referred to as "Kašana", and beneath a rocky overhang in the 70m deep abyss, the Partisan cyclostyle "Tehnika Krn" (the name of an old printing house, later known as C-32) was built in the cold and snow of December 1943.
A field kitchen and a sleeping tent were set up next to the hut, and a spare storehouse for paper was situated along the left side of the Zadlaščica.
A variety of gazettes, newspapers, leaflets, brochures, songbooks, and such like were printed here.

Working for interims of months, the cyclostyle system operated all through to May 1945.
