During my 3D printing, I experienced something awesome. I learned how to use Tinkercad and see how to 3D print. The actual 3D printer was really cool and it was cool to see how things print. Also, the 1871 tour was spectacular. All the technology was amazing, like the mirror that tells you your schedule. Everything there is so futuristic! The LEAP Innovations room and competition was very interesting. If I were to make my Paper Holder a real product, I would change a couple of things. The slots that I made would have to be less thick and I would add more slots to the holder. This is my reflection on 3D printing, and it was marvelous!
