Here's my model
Here's the reference image
I've tried using fillets, but it keeps giving me errors.
I can put fillets on your model no problems at all. The big issue is that you are never going to get your model to look anything like the reference image that you have shown because of the way your model is constructed.
Essentially, you don't have enough meat (thickness) in certain areas to be able to add the curvature that you need.
I'm sure that others will have different ways of doing this, but just quickly,
Design on Top plane and extrude,
Extrude through from the right plane,
Add strap blade...
Add full rounds....
Fillet to desired outcome, my example is only a standard fillet but using variable fillets will get you even closer to your reference image.
This was just a simple few minute quick mock up of how you can achieve a slightly better result. The wizards of this forum are sure to give you better ideas but I hope this gives you some insight and helps you nonetheless.............
Would it work if I just thicken it or do I have to model the whole thing again?
It's not up to me to tell you what to do, I can only give you suggestions buddy!
Sometimes we learn by doing, sometimes by mistakes.
How many steps does your model already have and how many more is it going to take to thicken it. Will thickening it give you the correct initial body curves?
Totally up to you mate...........
This is what I got. How's this?
Try this, may help!!
You can have soft edges in your rendered image of the part(if you don't want to get messed up in surfacing ). Just go to Edit appearance of your material -> advanced -> illumination -> scroll to last and increase the "round sharp edges' to desired dimension.
Are you happy with it? That's what counts!
Can you fillet the rest of it?
Notice the hole in the sides on the reference image appear to have an oval shape to them, how will you now achieve that?
I want to know how well it would be accepted by an employer. I'm just a student now so I would expect that many of my products are not professional quality.
That's a reasonable thought process.
I'm not an employer, but how about if you tried 2 or 3 different ways of modelling exactly the same buckle and see which way returns the best results. Get opinions from other students, your lecturer, your friends. Show them the reference image and then ask them which one of your models best represents the image.
As you are a student, I would have thought that you would have been shown the best practices for analysing a product and then deciding on the best way to break it down into a design method to achieve the best results. I only play with SolidWorks as a hobby and this was one of the things I found interesting to learn (by reading actually). This would surely help you apply some professional attributes to your finished product from the start I would have thought.
Why don't you try 2 or 3 different methods of doing the buckle now and post screen shots of each finished product and get opinions from those here in the forum, everyone was a beginner at some stage............
The buckle is very basic, although a surfaced version may take a little time unless you're very savvy with surfacing. You should be able to knock up a few different versions within an hour or two. As you go, you might find that your thought processes change, don't be afraid to try what pops into your head even if it leads to a mistake, it might also be a pure gem that saves the day!
I made one with an oval slot.
Absolutely no offence meant here, just straight forward constructive criticism.
Adding an oval slot as a extruded cut at the end is not good imho. You've forgotten about your original quest.
You need to look at ways of rounding off all of your existing edges. It's a buckle, it will be touched by hands, possibly little hands. Look at ways, like I showed you, of starting out so that you can apply smooth edges around the whole body.
I will attach the simple basic part I created if you want me to, but I thought it might be better to try to teach you how to fish rather than give you the fish..........
I don't know anything about buckles and not much about the fillet tool. I'd just keep researching what you are trying to make and read the help file to see what *every* option does.
After that it's just practise..
Generally speaking use symmetry and try to have your features match your design intent
This part would be a perfect candidate for a solid model with fillets added, then shell it.
Or alternatively, use surfaces to create the outside, then thicken it.
In a 3 second look at the picture that you posted, that is how I would do it.
Here is a model I came up with See attached file.

Since you are a student, I suggest you model each Dave Bear, Rob Edwards and Dan Pihlaja buckle as its own file.
Then compare each approach and your interpretations of them.
If you model bits from each of these masters, I think you'll lose out on the potential SW knowledge you'll gain.
Being a student means learning your lessons, nothing else, so concentrate on that.
Especially since these lessons are from three gentlemen who are #3, #10 and #21 in the forum.
You'll need much more than SW for any future employers, so by learning, you'll become more adaptive and by being so, whenever you do start off short, you'll accelerate in no time.
Hey Eric,.. in the spirit of Friday... and listening to music... here's a reference which will get all the gearheads excited!?
Ansys Structural nonlinear - Consumer snap-fit (Bag buckle) - YouTube
..and, a like to another fem site... (I think it has a STEP file?)
..and from there,.. a layout for your profiles...
You can also compare your efforts to the buckle models from McMaster (they're featured models, not imported geometry):
..and surfaces.... and trim... and...
Would a helmet manufacturing company most likely manufacture their own buckle or just buy them?

If the helmet manufacturing company exclusively made helmets they may or may not have the tooling/moulds to make the buckles, there's possibly a good chance though that they would buy them in bulk from China or Thailand............
I think I'll still try to model it myself for learning, but it's good to know that if it's for a job I'll probably just grab one that the company bought.
In your surface modeling I see these type of (sky blue color) curved surfaces. Is there any particular reason for having this surfaces?
Thanks for the constructive criticism.
Maha,.. the surfaces you see highlighted or glowing are due to a having RealView.Graphics turned On and you select the surface(s) within the selection manager (they slightly glow)
btw, I'm using 2014 in that example (magenta trim) but it looks a little different in 2018 (yellow trim but still show blue/glow surfaces).
Not about the appearance of the surface but the purpose of having this surface.
