The file 'Warhammer 40K Necron 25 Mm Round Base 3D Printer Model' is (stl) file type, size is 7.9KB.
I had purchased some Necron warriors and wanted to have a Necron inspired base. So, I made one in Tinkercad. These have a Necron symbol inscribed on the top. I tried looking up the symbol, but couldn't find any information on it. It may just be a generic symbol.
