The author remixed this model.
Moved the cord hole to the edge of the base so I didn't have to desolder my cord end to make it work, also made the hole in the center smaller to work with this cord adapter. https://a.co/d/awQaQcz If you need to make it bigger you can just set the print infill to concentric and when you go to drill the hole out it will be a clean hole what ever size you make it. Recommend using a step drill bit.
