Learning Slowly

Hello
  My name is Jon and I bought my Printer last year. It is an XYZ Davinci 1.0. I figured it looked pretty simple for my first one.
I have been pretty happy with it. I flashed it with the Repetier bios, then re-flashed it with the xyz bios as I could not get it to stick the print to the bed. Then found out part of the problem was a broken bearing housing on the drive side. So I enlisted my brothers printer also an XYZ Davinci to print me out a new one, Thanks Thingiverse and whoever modeled that one for it. It is currently happily printing a spool holder. I hope to learn 3D modeling so that I can design my own parts. How ever I work a ton of hours and don't have much time.
