I found this interesting. It’s a different view point than “buy the latest and greatest”.
Man I have never understood what people are doing to make money with a 3d printer. It’s an incredibly inefficient manufacturing technique if you need quantity of a part. So, how does that business even work. Who the hell is buying all those… green rectangles? What are they for??
There are print request sites where people will put up a print model and filament requirements and you can agree to provide them by X date for Y dollars.
Sometimes people need one offs and dont want to buy a printer, so they pay $50 for $5 worth of plastic/electricity. Sometimes other folk need 100 of something and pay $5/each for something like a green rectangle. With solar panels or cheap electricity, as long as you are making a profit after buying plastic and have the process tuned in, you basically have machines making $1-3/hr just running 24hr/day.
I run a small online store and make between $400 and $1,000 a month in profit.
I sell specialty phone cases that connects Razer jungle cat controllers like a switch. Also Galaxy fold cases that hold the new s pen. Other stuff too

Ah yes, the other stuff.
