Made using stabilized wood. The arbor was made with a 3D printer, using 9.5mm specifications. Commercial products come with metal arbors, but they are heavy and tend to slip, so I'm using this custom-made arbor! It was made to fit a Millionaire GS3000, so when attaching it to an Abu, Conquest, etc., it's better to use a plate. I'm also including a 3D-printed plate. The finish is beeswax wax.
