My 2 cents are that if the model gears (the hard part of the model) perfectly align with those of Ri0m0, give or take a rescale, the model should be taken down. Since the idea was not original from the beginning i’d dare say that if it is an original remodelling without reverse engineering of the technical aspects (see overlapping stuff with the original stl) it should be allowed. It should also be a matter of skills, did Ri0m0 and TNTBA ever publish similar models showing the evolution of skills required to design this model from the scratch up?
