Guide for Spool holder

I loved the spool holders by JohnSL and inserts by rpouetpouet. I didn't have any issues with the spools falling into the gap but the inserts keep the spool centered. I purchased a few spools from makergeeks and the rim was much wider so I made a wider guide. The gap is 5.25mm on this download. First time using sketchup to create something.
