How often do you make a sale on your stores?

With these third world prices I predict very, very few sales and incomes for you

Never had any sales can't really help you :p

There are literally dozens of things that factor into how frequently you will make a sale. Generally speaking, if you can make ONE sale per day, then you are doing better than 90% of the sellers here. That's something you should think about when pricing your models. Are you going to sell enough of them at $2 per model to get a payout at the end of the month? 99.9% of the people here will never sell enough products per day to justify a $2 per model price.

My average sales now is around 35 models per month. I agree the low prices wont do you any good. Low price does not grantee more sales, on contrary in fact, it makes people suspicious your probably selling rubbish, stolen or beginner models full of errors.

My average sales is 4.8 models per month, taking the entire past year into account. My best month ever was 10 sales :/

I sometimes sell 2 or 3 per day, the highest has been 9, sometimes I don't sell anything for a week on here but start selling on Sketchfab and elsewhere. It's a strange world that you can't plan out because you're at the whim of others.

Marketing is another thing, if you're good at it then you will sell stuff.

Keep your chin up and keep posting your models. Eventually, you will find your niche, and the sales will follow.
