Actually its esy to make, the inner diameter of the shell is 38mm, takes 5 A4 paper straps to make the tube or the shell. or the fuse I use a 6 mm paper tube with BP pressed inside, on the photo you can see its inner construction, its written in russian, but its easy to understand, the red layer is the pressed BP, it end with a conus, so it still burns after the BP layer in burned to the other side, thats provides a good ignition of the black-match ( orange strips ). Blue is the tube of the fuse itself. The red fluffy stuff is the BP+ 5% Dex, I mixed it with water, nd put this on the ends of the BP layer and the black-match, that provides good ignition of the BP layer + no flash powder can get in through the black match side, I dont know how to call this mix of BP and Dex that is used for helping stuff ignite. In russian we call it "Подмазка" and it sounds like "Podmazka" with letter a like in the word "auto".
Also the black-match will be " Стопин " in russian, it sound like " Stopin" with letter I like in the word " pin"
