Help my 3d dream become real!

I'm 25 years old. Living with Cystic Fibrosis makes getting a job difficult, maintaining a job even harder! I've been involved in 3d development since 2005 when I received my first computer, and have been addicted ever since! I'm very passionate about fixing, repairing, and developing better alternatives for anything. I first experienced 3d printing winter 2013, when I contacted a local printer to produce a design I emailed him. I want to help others with their visions, improve existing things with revised versions, and produce parts for things that are no longer manufactured. I want to make life that much easier, and create solutions that change everyone's daily life. This is the step I need to succeed, and flourish in life. My target goal is $700, that will get my a printer, the materials I need to produce the rewards, and ship them! Anything over $800 will go towards additional printing materials(colors ect), and or a higher quality printer, in turn allowing me to print higher quality rewards for my donators! Please help me obtain this goal! Thank you!
