Your first? That's excellent. If you ever build that model again, you can search for forums and find how you can round the front out using a metal Dowel, with a Ball end, or something else with that shape. If your printer uses "Pigment Ink" you can actually moister that piece and run it smooth against a firm but rubbery surface. Great job!! Pigment Ink does not run when wet, Dye ink does.
