Where can I sell my models and maps?
Is there someplace where I can sell my models and maps. Is it on dev forum or some other place? Can I get scammed there?
Yes, you can. But there is a risk of being scammed. You can try making twitter posts. I’d put this in #help-and-feedback:building-support.
Is there a Roblox system to do it. Like maybe putting price on a model or something.
Alright, well good luck! 
Yes, it’s possible to sell your maps and models. Official is it not allowed if you follow 100% The ROBLOX TOS but roblox don’t do anything about it.
Well, yes, there is a possibility of users getting scammed in discord servers as these sorts of things happen quite often through a wide variety of developers. Instead of selling your models consider moving into doing commissions so you can have models that you could showcase within your portfolio.
There used to be a subcategory on the forums called; Asset Marketplace which allowed users to sell models - maps and other sorts of creations which got removed a while back. There are many of communities servers that do allow you to sell your builds, a known one such as (Hidden Developer).
You should take the opportunity to do commissions rather then making a few models/maps and selling them right away.
Roblox is very fickle when it comes to these kinds of things, theyre pro builders making robux but make it very hard for us to do so, best thing to do is just avoid being super public about things, theres tons of sites that let you sell assets easily, I cant provide a link but if you look you can find them
Well you can’t because there is a large amount of % of you getting scammed, by a bad person.

If I were to sell a map, what category would it be?
That’s a sure way for a game to get taken down for “scamming”
