Better Printrbot Simple Metal Spool Holder --------------------- I Fixed [Mayermi ](Http://Www.Thingiverse.Com/Mayermi/About) Design For His [Printrbot Simple Metal Spool Holder](Http://Www.Thingiverse.Com/Thing:302633). Things I Did: - Resized The Holes. They Were About 13.1Mm And Should Fit A 12Mm Rod. I Made Them 12.5Mm. - Changed The Space Between The Two Holes From 71Mm To 70Mm. - Alterted The Fase To 50° So It Can Be Print Easier Without Support. - Designed A "Washer" For The Bearings. Now The Spool Can'T Slip Off The Bearings. Bill Of Materials: - 2 X M8 Screws To Secure The Holder - 4 X M8 Screws (8X45Mm) - 8 X Washers - 8 X 608Zz Bearings - 8 X M8 Nuts I Stacked Them This Way: Nut - Washer - Bearing - Bearing - Washer - Nut.
