This supports the Vypers original spool holder to prevent it from sagging to one side when a full spool is used. I have tested several spools (eSun, Sunlu, Overture etc and they fit).

This support tower is very easy to print (no support needed) and it simply sits on either side of the original spool holder.

Recommended to print in:

PETG
0.20mm Layers
No Supports
Small Brim for extra adhseion.
