For the KnitPro Ball Winder SKU 10941

The idea was that you could dial down the diameter for smaller balls of less/lighter yarn. but it will also let you tweak the length of the spindle

v2 - hollowed out to avoid the nut that holds the larger flared base to the winder - required no supports to use
Set a thicker wall (3mm worked well) as too thin and I snapped the spindle off at the base getting it off the printer

This is the first time I've uploaded a customisable file - I'd love to hear your constructive criticism and suggestions.

Note: I actually have the K1SE but it's not an option to select on Thingiverse
