We are definitely going to need 3D Printers for whenever we settle on Mars. You can print a tool/machine/kit and later recycle/repurpose it into something else! Saves waste, delivery time, and money involved in the conquest of space.
A store at The Staples Center is having this service where you can customize your own Kobe shirt. There’s a paper you fill out, what logos you want, what typefaces you want, what message/phrase/name, what locations, etc. Pretty neat!
