Hi, I am new to 3D modeling and forgive me if this is already somewhere on the forums but I couldn't find information on designing your own sintershell. I haven't been happy with the results when I've used sprues so I thought I'd give the automated sintershell a try. It did cut the cost but still seemed to use a lot of material. I was considering making my own shell made up of some sort of miniature objects that I could just cut apart because it seems like such a waste. What exactly would the specifications be for designing a sintershell as far as thickness, escape holes, etc.?
