So I had a 15% off coupon from eBay today and decided to go ahead and take advantage and buy a 3D printer. I had been wanting to get one for awhile, so I pulled the trigger. This one is pretty big and isn't supposed to take too much to set it up.
Anyone else out there got one? Any pointers on some good shareware? Good places to find .stl files?

I built my own Prusa-style printer a year ago. It's great. I'm constantly taking it apart and making improvements on it, a lot of those improvements made with the printer itself.
You're going to find a learning curve, so start slow and don't get discouraged. Here are some recommendations that I all learned the hard way.
1. Join a support group for your specific printer. If you can't find one for your printer, try a general Prusa printer group (your printer is a Prusa design).
2. Watch all you can on Youtube. Many people have done what you've done and you can learn from their mistakes.
3. Start simple. Pick a material that's easy to work with -- I suggest PLA -- and stick with it until you have enough experience to go to more complicated materials like NinjaFlex and PTEG.
4. It's tempting to design your own stuff and if you're good with a CAD program don't hesitate. But, there are literally hundreds of thousands of ready to print STL files for free on sites like Thingiverse and MyMiniFactory. Download them, slice them to create G-Code and print away.
5. Pick simple prints at first, little or no support material. Support material can be problematic to remove after a print is finished and who needs the frustration when you're first learning.
6. Start with a free slicer program -- Cura or Slic3r are the most popular. Learn about how to tweak those settings before investing money in a more powerful, and costly, slicer application.
7. Have fun ... there is so much you can make and many ways to use your prints in much more complicated manufacturing like metal casting.
