I, through the use of google translator, have joined a Russian CNC Forum. http://cnc.userforum.ru/viewforum.php?id=13 There are some truly remarkable artists there. Look through that link at some of their finished products. This is one that I am in awe at http://uploads.ru/LEIsR.jpg. It is a very strange forum. Not friendly to newbies. I have already been banned once, for not translating my post. They have tons of files to share, but membership requirements have to be met. But there are tons that are shared anyway. They are for artcam and or STL mostly. But some grayscale depthmaps too.
