> 3D printing will likely never enter the mainstream. I'm going to argue that it still might. I've been at it for about 5 years now and when I started printing my local Micro Center didn't carry anything related to 3D printers. Then they picked up the Ender 3 a few years back as the one printer they offered and they had a dozen basic color options of filament on the end of one side of an isle. Today that same store stocks at least 6 different printers on display and there's one and a half isles of a variety of filament options and another half isle of parts. And while Micro Center employees are usually more technically inclined than other retail employees, they themselves seemed to have gone from wondering what this odd Maker enthusiast carried up to the register to initiating conversations about your selections and comparing them to their own purchases. They wouldn't dedicate the floor space, let alone expand it continually and invest in larger and more expensive inventory if it wasn't selling at an increased rate. It's still a niche maker/techie hobby of course, but it's expanding more rapidly now than ever before.
