All the objects here are made to be subdivided, and therefore are not locked in at any predefined level of smoothness. I have also tried very hard to keep the objects joined together where they would be in real life, instead of the usual trick of intersecting raw polygons into each other. This kit is offered in a few different configurations. Click on my seller name meshmill to see the variants. I advise you to carefully examine the very many previews I have provided above as all of them are in HD.
