Printrbot Filament Holder

1. To upgrade your printer, download the Hatchbox Filament Mount STL file if you have a larger print area, or download the Center and Arms files for printers like the Printrbot Simple Metal. 2. Always download the Filler STL file as it prevents the unit from flipping off the metal hook during printing. 3. If you downloaded the Arms STL file, separate it into parts in Cura and print each part individually, then print any other downloaded components. 4. If you printed individual parts, sand the connectors together; otherwise, skip this step to assemble the unit. 5. Mount the unit on the Printrbot hook with the arm featuring a hole facing your extruder. 6. Lift it up slightly and insert the Filler below the top print layer on the metal hook. 7. Place the spool on top, threading the filament through the designated hole. Note: I have also included IPT files from Autodesk Inventor for those who wish to refine this setup.
