This is a 45 Degree Spool Holder adapter for the filament spool holder provided with the SV01.

I personally need this because my work space did not have enough clearance vertically.

To assemble this, you will need 1 extra T-nut than provided with the printer. Use this printed filament detector holder to free up a T-nut.
