I recently bought a cnc machine, a very good one, and i'm starting to get used to it and making different shapes and cool stuff out of it, I saw in a facebook group, some people that are making tons of money with their machines,so i said why not i make some profit too, i'm thinking about using ebay or etsy, but the thing is, what should i sell? i can make plenty of stuff with my cnc, but what do people buy the most? i don't wan't to lose resources or materials on objects that will stay in my garage while the dust eating them, i need ideas , please help.
