These are scanned parts with some cleanup to ensure fit. The peg on the wing is slllllllightly larger than it needs to be due to how the original hole can wear down over time and become loose. Light sanding will allow it to fit and rotate just fine. Peg for the cannon and the hole in the wing for it are angled to allow a clicking rotation as well so it naturally angles straight ahead.
Hard to see in the pictures due to flash, but the sticker and panel lines are included in the file and will print if you go at a high resolution.
Best printed with a high infill and supports. Stand the gun on its end with the hole pointing up to keep from having to clean out the hole. Stand the wing straight up like a shark fin as well. It'll use less supports and leave a nicer finish from what I've seen.
More parts coming eventually!
