..only get a 3D Printer if you are willing to learn CAD. Without the ability to make the design for the object, the Printer itself is useless. (Fusion 360 is the best – and it’s free). You also need to learn how to use the Slicer software. Once again, free (Lychee)..
..you don’t hear much about Endicia anymore, Stamps.com pretty much dominated that market..
