r4pt0r yes you get the idea, Ideally, it would be great if you could save the ship or detail directly from the game in format ready for 3D printing. dunno if this is possible? but I believe that if one import details to game then one can export it back ))) as simpler solution - If I understand it correctly - modders and developers themselves make parts for rockets (tanks, engines, etc.) in 3d Max or another 3d editor. after which pats are imported into the game. so it would be great if modders or developers could provide access to "original" model in the right format. may be sell them in shapeways or thingiverse - one by one or as a set of parts, (like the standart parts from KSP all at once). standart Parts is enough to build any rocket you want. plus modders could add with new parts. first you build rocket in KSP game, play with it enjoy the ride, then if you like you can recreate it in real life and put on the shelf and have memories). that would give many opportunities - developers and modders could add variety of spare parts, make some money selling Parts (models) for rocket, players could download and 3dprint these parts and enjoy building real KSP rockets at home. thus bring KSP to real life. - everyone is happy.
