Few weeks ago, while I was in Cuba I have announced the development of 3d cloning based tools, at that time I have tried unsuccessfully to upload some testing videos. Well, here’s the real deal 
Still is on early stages of development and many things will be polished, but the possibility to creatively clone features of the models (or libraries in the future) is worth showing. Unlike booleans that requires a lot of tweak and manual positioning to seamless bled with the base mesh this tools is very fast and allows to freely experiment with your models.
I hope you will like it!
