These are spare plugs for the EEW 6 Sectional Bobbins. Plugs come in a 6-pack of the selected color, enough to fully replace the plugs from your bobbin set (a 3-bobbin set takes 4 plugs and comes with 2 spares). Please note that these plugs are only compatible with the original style of EEW bobbin shown in the product images. You can use tape to secure the bobbin inserts to the ends of other styles of master bobbin, or pieces of scrap yarn to tie them together These plugs are printed in high quality, eco-friendly, industrially compostable PLA plastic. If you would like to download the STL file for free to 3D print your own plugs, you can do that here. These STL files were designed by Maurice, the owner of Dreaming Robots and engineer behind the Electric Eel Wheels. Color options Click here for a gallery of available colors. I'm not picky: Whatever's currently loaded in my 3D printer when you order it. Could be any color, or stripes of multiple colors.
