I have been 3d printing since mid-2016 and have made a few models that might be useful if you are interested you can grab any of my models I could be bothered to release on my profile at printables. I previously released models on Thingiverse but I am not updating there anymore.
Over the few months that I had the printer I changed it quite a bit.
3D Printer Aug 2016 Its a running gag that most of the things you print on a 3d printer are 3d printer parts. This turns out to be all too true since 3d printer parts are both useful(for 3d printing) and give you a sense of having accomplished something right away (since that part is useful right away).
