In case you are not already aware by the mentions in my other essays, I am big into 3D modeling and printing. I have an Ender 3 Pro that I have done some major and minor upgrades on, including a direct drive mod and a better knob mod, and I am also hoping to install a CR touch and a filament run out sensor. The long and the short of the matter is, I am really good at using my 3D printer and I really care about it. I’ve also made some designs that I know are unique and valuable that I have sold in the past. I run a sort of very small business selling my 3D printed items, and the income is very inconsistent, but I think I could upscale to sell my products online. My two big money making designs are a very simple phone stand and some fairly complicated nintendo switch joycon grips, the most versatile and cheapest of their kind. I can’t say exactly how much I’ve made with these items, but I am fairly certain that I have made at least one-hundred and fifty dollars between the phone stands and joycon grips. I would like to eventually start selling my products online through Etsy, eBay, or maybe my own website, because then I can sell my joycon grips to anyone almost anywhere. In theory, that could be a really successful small business endeavor, and possibly bring in a fairly large amount of income. In conclusion, I think that a 3D printing business could be a profitable and achievable small business that I could potentially start, even at the relatively young age of thirteen. With profits from this business I can also theoretically upgrade my printing setup, and so expand my printing capacity that way.
