About this 3D model

I had some spools that were too wide for the Printrbot Simple Metal Spool Holder, and I didn't like how "raw" filament would slide off the end as well. I tried making a similar design that was wider and had a nub at the end to hold things on, but they were too hard to print - so I printed a "sleeve" to go over the Printrbot Simple Metal Spool Holder. Probably worthless to anyone who didn't already print the original, It helped me out so I thought I'd share.
