Hey Fist time posting here, and I am currently working on printing the SRS99-S5 AM Sniper Rifle. I am going to be making a 53" long version when I am done the pic I have posed here is of the muzzle break and it took over 3 hours to print. As I get parts done I will be updating this post. I will also be posting the sliced model in the armory for all to use along with the instructions for the best print. I was printing this at my local maker space.
