I'm A Simple Cattle Rancher Getting In To 3D Printing. Slowly earning learning how to design, and I have no idea what I'm doing but I love doing it. Given that I haven't had or used a computer in about 15 years until I got into printing, it doesn't seem to impossible. Just got a Crazy3Dprint CZ-300, and I'm trying to figure out some upgrades to print. I will post some as soon as I can.
