we just got done putting this one together - there seems to be a few pieces that are misfit in the back - or it could be just me! Regardless, it came out great! I'm not sure how to put any pics up, but I will see if I can figure it out.
Thanks for mentioning it in the comments, I encountered the same problem when looking over the file. There are a few pieces in the back that need to be divided further but since I knew it in advance thanks to this comment I made the aditional separations to it before printing and everything worked fine!
