Super smooth filament rolling using a standard Skadis straight hook.
The bracket is in the centre of gravity of the spool making it unroll very smoothly. The pointy end of the hook keeps the spool from falling of and the slat used to fit that pointy end through is closet with a snap fit piece, making it reusable. Fits all my 750gr spools.
