BuMat Spool fitting

The outer diameter measures a full 57.5 millimeters. The inner diameter checks in at a snug 32 millimeters. Specifically designed to fit perfectly, it's built with the Printrbot Simple Metal - grip with spool holder http://www.thingiverse.com/thing:446649 firmly in mind. To prevent the part from buckling or lifting up from the print bed, use a solid 2mm brim and adjust the travel speed to a leisurely pace for an ultra-smooth inner circle finish. Having personally used my trusty Printrbot Simple Metal to churn out some stunning prints of PLA with a slow and steady travel speed of 20mm/s, I can attest that remarkable results are entirely within reach without any brim removal necessary. To make your own modifications or adjustments a breeze, the construction lines have been thoughtfully left intact inside the .dxf file for your reference and future use.
