Way back in 2014 I made this mashup of Thingiverse user MakeALot/Mark Durbin's (he listed his name on Thingiverse) Eiffel Tower Bud Vase (CC-BY-SA4), his Big Ben model (CC-BY4), and his model of the London Monument To The Great Fire (CC-BY4). Now the funny thing is that I exported it as Collada (DAE) back then (I used MeshLab) and it was still buggy then. MakeALot himself loved it and made an STL port (I later fixed THAT one, which is key), but was able to license it as CC-BY4 because HE made ALL the inputs. I'm fine with that outcome, because this model is a fixed version of THAT one. So, THAT is why this model is able to be CC-BY4 rather than CC-BY-SA4, because the original creator of my source model was very, very, generous and approving of my merger of his 3 monuments.

Ideally you would want to use this in your skyboxes or such, or as an actual building in a sci-fi map. Like with my other model(s) this is untextured, because 3D printing. It would look very epic in a game though when given textures.
