I was very excited to find this in kit form, simply because it's different. Maybe also because I'm the first and only numbnuts in the world to actually buy one (got it from Shapeways...it cost a small fortune!).
The kit is 3D printed. Shapeways weren't even sure they could print it when I placed the order..
The windows are supplied as a plug which needs to be vac formed. So I lashed out and got myself a dental vac form machine. Now I need to find some 0.1mm clear thermoform plastic, but that's another story..
Today I primed it twice with Mr Surfacer 1000 out of a rattle can. There are some striations from the printing process still visible, but I'll be sanding it back before I add another coat.
