This is pretty damn amazing. That looks just like the one I held at SDCC. If you do a run of parts I'd be in line right behind KoCo.
I used the basic measurements Feig had provided , but most of it I just did by eye...which is a little deceiving in 3d sometimes. I actually totally screwed up and used the wrong size pvc as the handle base...so that side is kind of wrong...the tubes on that side and the t-shaped thing should all be a bit bigger. Which means the rest of the base is slightly too wide too. I didn't notice until I printed the handgrips and saw how off the handle one was compared to the other as they look about the same size on the real one. So...instead of redoing it all...I just made a little patch piece to put around the handle pvc to make it bigger between the handle and the gun base. I don't think most people would ever notice that...but I know it's all too small!!!
I love the coloring! Can you give some details on the paint you used and the aging/weathering techniques you used? I'll be painting my dome in a week or so and would love to get some pointers from you. I tried some rustoleum flat metalic nickle and it is way too "sparkly".
Currently I have sanded and primed parts and the XTC-3D has arrived and it has some scary warnings so I will have to take my time and do some comparisons.
I think I actually used that same exact paint...and it was too sparkly!!! However, that didn't really matter as it was kind of just the base.
I went over top of that with silver RubNBuff which is awesome for giving a good realistic metal look.
After that, I went over it all with lots of black acrylic and water...wiping it off, adding, wiping, blotting, dry brushing it in detailed areas, etc... It took a little time and love, but it is worth it.
I actually don't use anything like XTC-3d...but I am fairly new to the 3d print stuff. Maybe I will try it someday...but I am too impatient for some of those steps!
I just did some basic sanding, and then went heavy on the paint with several layers/coats.
