The 3D-printed pieces really turned out nicely the Dremel Ideabuilder printer. They were printed at highest quality, with 3 shells and a 35% infill. I started sanding the radar eye last night and the PLA sands beautifully. I am using a 120 grit sandpaper on my Dremel Multimax tool.
I plan on printing the holoprojectors as well since I found Vickers Viscount 3D print files that someone had posted online. Thank you inter webs!
