No sir!
Thank you for thatby the way, as i'm purchasing several products from you, half of which don't even exist yet, and want to get them altogether, you can send my already made launcher to somebody who needs it right now, i'll just wait for that second batch
. As I said before I plan on starting sending launchers out once I get final confirmation on batch two from the caster. I know it might seem a bit weird but it's to ensure equal quality across the board. 
Dang it, you got me there, but I have an explanation. I didn't want to 3D model that in as I figured the printed part would be too easily breakable. The plan was to model in an insert hole and then include that as an actual piece of metal. Don't worry, it'll be there
So the lines are a product of how I had to model it, and 3D modeling in general. All surfaces of the model, even curved ones, are made up of little triangles and facets. For example the handle looks really smooth along the back, but not along the front. The smooth part is still made up of a ton of different facets, but the program "smooths" them over to be not visible even though they're there. I had to model the barrel housing in a way where the triangles actually show up visibly in the illustration (it ended up this way because the front of the housing and the back are different shapes, thuse I couldn't just form a uniformly curved surface), but the end result will be a barrel housing that should look smoother than the illustration would lead you to believe.
