Scotch Packaging tape dispenser

I cleaned up arabon's nice model found here:

There were a few portions of the model that weren't complete which caused the Makerware slicer to produce some strange artifacts.
The holes are patched now and the print looks great!
Edit: I printed arabon's model to find that the outer diameter of the holder was off. I inverted that so it now fits a standard ~76mm (3 in. if you swing that way) roll of packaging tape. The new model is now uploaded in place of the old one.
Edit #2: The teeth easily break off and need to be reworked a bit. Printing with a higher infill or with a stronger filament (nylon) may prevent this from occurring. Suggestions and comments welcome.
