EEW Nano Wing Bobbin disc

This is a redesigned nano bobbin disc avoiding the need for supports due to a change in the shaft socket it matches the original profile and so will work the same. The shaft is again redesigned to have increased area at each end as I found the standard ones often failed during printing as the adhesion to the bed failed. These shafts must be glued as they are not a tight fit.

If you want a tight fit the discs will fit on the standard nano bobbin shafts tightly.
