First ever model, suitable for 3D Printing?

Not sure if this is the correct subforum or not, apologies if it isn't.

 

Hello, I've recently installed an aftermarket fog light kit in my car and I want to mount the switch in the factory location. The factory switch hole on cars without fog lights are plugged with these plastic coin holder inserts (first photo attached shows both the switch and the insert) so I wanted to try modelling a replacement insert that has a rectangular hole in it for the switch. I made the model shown in the second image over the course of three days learning in FreeCAD. It has the top ridge, the rectangular hole, and the little bumps on the side that you can't really see on the factory insert but they're there for keeping the insert attached to the center console, and I intended on sanding them down bit by bit until they matched the factory insert because I have no way of measuring something so small for modeling. All the other measurements match the factory insert as closely as I could measure with a standard tape measure though.

 

This is my first time ever modelling something, and I do not own a 3D printer but there's a store in a mall near me that advertises 'custom 3D printing' so before I go talk to them about whether they could print this for me, I wanted to ask whether or not this model is even suitable for being printed, or whether I would have to modify it at all before they would be able to print it? The flat face in the top right of the insert image is designated as the 'bottom' but I know that the rounded fillet along the edge could possibly cause problems, same thing with how the bumps on the sides hang out over the sides. I'm a bit anxious about this model since I've never done this before, and I didn't wanna go all the way there and ask them to print it only to look like an idiot by giving them a file that can't be printed or would have trouble being printed so I wanted to ask here first in case I have to adjust it at all.

 

Thanks!

The fillet/edge blend on your bottom face isn't ideal, but you can give it a shot, it might work fine.

The overhanging clips will need support, but that is managable too.

 

Dont be scared, give it a go! The beauty of printing is that its cheap and easy to iterate.

I considered maybe separating the model into just the top edge section, so that it can be printed with the fillet facing up, and then the bottom wall section separately so the clips require less support, and then just gluing the two together. Maybe even getting rid of the angled bits on the clips and just turning them into squares, then just sanding those angles into them after the fact since I was planning on sanding them down anyway. I guess I'll reach out to the store I'm planning on going to before I actually make the trip over there to see what their thoughts are, but that will take a while because it seems they're only open on weekends. I guess worst case scenario I can prepare a file for both the complete piece and the separated piece and let them print whichever will be easier.

Thank you! I'm hoping to get my own printer in the future to keep creating small stuff like this but it isn't really in the cards for me right now. We'll have to see what the future holds I suppose.

Ideally replace the fillet with a 45° chamfer. Sure it won't be rounded, but it may look nicer since it'll print cleanly. Looks fine otherwise.
