Some here know Cults3D, for those that don't it's a "design studio" for independent people to upload their designs for others to download & print on their own home 3D printer. Most designs I've looked at cost between au$5 & au$80. It is well worth a look through the 2.2 million designs on the site using the search engine for your preference of model. I found one major item & 3 accessories for my preference of 1/35th Israeli tanks. Have bought two to be printed by a local hobby business in the next week.
