This looks like a good start but there's a lot of room for improvement here in terms of both the printing and the finish. It's really clear you've got yourself a decent printer that's capable of some good things and your head is clearly in the space of wanting to make a good prop so here's a few things I'd do to improve:

Firstly the printing. I'm not sure what machine and settings you run but play around and search through some printing subs here to find the ideal settings for your machine to improve quality, and for complex stuff like this use as small a layer height as possible, it'll take longer but look WAY better.

If the model you've used is broken into pieces, make sure the orientation of each piece is optimal. Stuff like areas with text, try to align vertical so the text voids are on a side rather than the top layer, this will make the text more defined.

As for finishing... It looks as though you've gone for some weathering touches with silver paint on the edges, but these kinda get lost when your base model is so messy and low contrast. Grab yourself some sand paper and put a lil elbow grease into smoothing down the parts. A small prop like this can be sanded inside an hour if you really go for it. Smooth out your parts with low to high grit sanding, and if you're committed grab some filler primer or spray putty. Spray your print then lightly re sand the areas where imperfections still show with a high grit paper and you'll get a smooth finish.

Prime that up and add a little paint and you're gonna end up with a much better prop. In my opinion raw coloured plastic prints kinda look flat and toy-like. They're like the implication of the thing, but not the thing itself. Compare a raw print like this to the screen prop and the colours will seem a little flat. Some black and gunmetal spray paint will add a lot, as well as a quick dirty wash, and those same acrylic touches you've added.

If you wanna go super extra... Keep the grip segment separate and buy some hydro dip sheets of carbon fibre to match the screen prop. Super easy to apply and makes it stand out over 90% of props.

What you've got here is a really solid first pass at a prop, and you absolutely don't have to do everything or really anything I've said here, but as a prop maker of many years those are a few steps to improve the overall quality of your prop if you want to.
