About this 3D model

Second attempt at uploading my entry for the 3DPN Spool Challenge. First try would not finish doing a "software check" for some reason. There should be three pieces... two hooks and a hanger. I put all three in one stl file the first time. Maybe that's why it didn't work. This time I put them in separate stl files. Hope that does the trick! Instructions: Print two of the "hangers", and one "hook". The hangers insert into the two square holes in the back of the hook piece. Then the whole assembly can be hung on the wooden beams. That's it! :-) - Brian R.
