Filament Spool Winding Handle

thingiverse

This convenient handle can be attached to the side of an empty filament spool, allowing you to hold filament samples. The handle makes it easier to spin the spool and wind the filament into place. Drill a 10mm hole in the filament spool, ensuring that the handle will fit snugly inside when attached. You may need to make the hole slightly larger to accommodate the spindle - wiggle the drill gently! Glue both halves of the spindle together using superglue. Insert the spindle through the hole and apply a few drops of superglue to the inside of the spindle cap, securing it to the filament spool. Snap the handle into position. Use your spool holder on your printer to wind filament onto the spool. Printing the spindle in two halves, with the joining surface facing downwards, ensures that the layers will be oriented for a stronger bond when the handle is attached. I have included the complete design of the spindle for those who prefer not to glue the halves together. Update: The diameter of the inner flange has been increased to provide a larger surface area for gluing it to the filament spool. Use version 2 files for the spindle, while the handle remains unchanged.
