I recently completed a build of a 3D printed ANH E-11 which I modeled and printed myself. I used PETG filament and printed all the parts on my Creality CR-10S printer. I picked up some good pointers from justjoseph63 and his excellent tutorial on smoothing a 3D print:
PETG is a wonderful material and sands beautifully. Yeah, it was a lot of work, but not as hard as you might think. I printed my parts a standard resolution (0.2mm/layer) which is already fairly smooth. I sanded with 100 grit followed by 220 grit. I used putty to fill in any blemishes or scars left from support attachments and sanded again with 220 grit. Instead of using the XTC-3D epoxy in the tutorial, I used multiple coats of Rustoleum Crystal Clear spray enamel, which I sanded to a very smooth finish.
For the topcoat, I used Rustoleum 2X flat black on the sterling barrel and frame/end cap. I used Rustoleum 2X matte black on the scope, Hengstler, and grip. I also sprayed the grip with clear coat to give it a glossy finish. I painted the fire control group housing and bolt with Testors steel enamel and used a flat black acrylic paint and water mixture to tone down the steel color and add dimension. I used a formed metal spring instead of the printed spring. I highly recommend doing this.
I did a bit of light weathering on the finish. I used acrylic silver to touch the edges of the Sterling and dry brushed sparingly on some of the flat surfaces. I blackwashed over this and used a paper towel to get the finish I wanted. On the scope, I touched up the edges with acrylic antique gold and used a white crayon to fill the text on the eyepiece. On the Hengstler, I painted the logo window acrylic antique gold and blackwashed over that until it was nearly hidden. I also painted the number display.
