I was tired about the limitations of the original turn table. Filament spools with smaller inner diameter (i.e. Taulman) could not stay on the table.

This new turn table is good enough for small and big spools and would also easily keep heavy rolls on place.

Fits perfectly into the original bearing. Bolt to glue into the table.
