I've been contemplating the nature of the rat race lately. If you can do it all, and you're enjoying what you're doing, why should it scale? If it's your side business, I presume you want it to remain that way until there's enough demand for it to be your main business -- and even then I wouldn't want to scale beyond demand.
> why should it scale
Because you need your business to be big enough to pay your bills, not just theoretically net positive.
I have made some designs that I thought of selling too. For something like that to work, you need thousands of customers over the time.
It's ok to spend an year or two of weekends working into something that can replace some of your main income. It's really not ok to do that for something that can't.
Why to scale? Because hours of work for $300 is not worth it lol.
I agree, and a big practical reason I walked away was that I was spending my weekends and nights doing this, and there were other hobbies/interests I wanted to pursue. After so many order, it was also getting pretty boring to print the same thing out, over and over, but I could have always raised prices and decreased order that way.
I'm still 3D printing, but now focused on problems like dog and kids toys where I can give away the results.
