Hi guys I'm still fairly new to 3d printing and I was just wondering when I download a cad from thingyverse or something similar are the cads set to there proper height from the designer? For example I wanted to download a lightsaber replica and when i open it up with Cura it seems to be way to large and i have to scale it down but i have no idea how big it has to be and it seems to be a lot of work to work out how big each of the 14 sections need to be to get the proper height if you know what i mean. I also wanted to print a robot but if i have to scale it myself i have no idea how big each peace needs to be before printing the rest of it to make things fit.
