1.5" Diameter Hole Filament Holder

I bought some non-MakerBot brand filament for my MakerBot 2x, and it didn't fit in the filament spool holder, so I created this one to hold it! It is made for a filament spool with a 1.5in diameter hole in the middle. It fits very well into my MakerBot 2x printer, just like the ones that came with it. This thing was made with Tinkercad.
