QIDI Box adapter for filament rolls with less diameters like SUNLU rolls

This adapter is designed for the QIDI Box, which is a multi material system.

Some filament spools—such as SUNLU rolls with a diameter of only ~195 mm—are too small to rest properly on the front and rear rollers. Instead, they sit on the base of the enclosure, preventing the spool from rotating freely.

This can cause issues during filament unloading, as the spool cannot rewind due to friction with the housing floor.

The adapter raises the rear roller, allowing smaller-diameter spools to sit fully on the rollers. This eliminates drag and ensures smooth rotation, enabling proper rewinding when unloading filament.
