Better Printrbot Simple Metal Spool Holder
I fixed mayermi design for his Printrbot Simple Metal Spool Holder.
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.
