Welcome to the 405th!
That looks great for a first prop build! The lettering on it looks really clean and impressive.
You did a good job on clean up, but sometimes you can save yourself a lot of cleanup time with how your parts are setup on the build plate. As a general rule of thumb you want as few of your outer part faces touching the build plate and supports as possible. If you have any specific questions or concerns with 3D printing or prop building let me know and I'd be glad to help you with them!
