finally finished my smoke/dust stacks for rotary kiln. this is end wall of building they will fit on, no weathering on wall yet i am just getting started on building. it’s crazy i have about 100+ hours in each of these things. the 3d printing of the stack itself was about 40+ hours each! btw i put the stacks in 3d repository if anyone is interested u can build several configurations with the pieces, thanks to dennis for his efforts on the repository
