About this 3D model

This is a spacer to center BuMat brand spools of plastic for my Simple Metal Spool Holder available here: http://www.thingiverse.com/thing:322923 . Fits these roles of plastic: https://www.amazon.com/s/ref=bl_sr_electronics?ie=UTF8&field-brandtextbin=BuMat&node=172282 . It should also fit any spools with an inside diameter of around 57mm. . UPDATED 2014-08-04. I increased the diameter slighter and raised the edges for a more snug fit. Lightly sand if too snug. . I also made spacers for Printrbot and SainSmart brands of plastic. If you want a customized spacer for your favorite brand, send me the inside diameter of your spool. .
