When the filament is placed on the spool core, the inner filament end slides into the hole provided. Then the cover is put on and fixed with the screw. The spool core has 6 small pins and the lid has recesses so that the lid cannot rotate. The slots are always exactly over the cable ties of the filament wrap when assembling. The screw (the red part in the photos) clamps the two parts of the coil together as if the coil were one piece. The screw closes flat with the surface, no protruding parts, coils can be stacked. A drop of sewing machine oil or silicone oil on the thread works wonders.

On the circumference of the cover there are three filament clamps in which the filament end can be fixed. The clamps with the larger radius are intended for normal filaments (PLA, ABS), the smaller radius is for rubbery filaments. No protruding filament ends, coils can be stacked.

If you stick a piece of carpet tape on the labeling field, WITH the release paper (silicone paper), then the label can be replaced as often as you like. Without additional tags, without Velcro.
