Ashford Jumbo Bobbin Resized Core Piece

thingiverse

I created this bobbin core piece because I thought the original one was too small in its outer diameter, with a center hole that was also too small and threaded parts that were too short to get a snug fit with the bobbin discs. I also designed another version of the core piece with a leader yarn hole. Here are the printing settings: Extruder temperature at 215 degrees C, Bed temperature set to 60 degrees C, Shell thickness is 3, Bed adhesion type is Brim, and Supports are set to Lines touching build plate only. Before printing the bobbin core piece, it needs to be rotated 90 degrees so that it's in an upright position.
