Hello I have made a 3d model available for purchase on cgtrader.com. It is a simplified version of a 25 mm chain model I did a while back. The model has lots of nice details and comes in two formats, obj and step. The step version costs a little bit more. If you are interested please have a look for yourself. http://www.cgtrader.com/3d-models/we...25mm-chain-gun kind regards,
