After printing is completed, you will have one wide piece (1×), one narrow piece (1×), and two spacer rings (2×).

Locate the locator (the small block on the wide piece). Align it with the notch on the inner ring of the filament spool. Insert the wide piece into the filament roll.

Step 1: Insert the narrow piece and align the grooves of both pieces inside the spool until it is firmly pushed into the wide piece.
Step 2: Once it is firmly inserted into the wide piece, rotate the narrow piece clockwise until it locks into place and you hear a click.

Step 1: Make sure the spacer ring is installed inside the spool (under the triangle).
Step 2: Tear off and remove the plastic strips.
