Detachable Hook Spool Holder Design

Hi viewers, I have designed my own version of spool holder that is lightweight, detachable and easy to be stored.Moreover, it able to fit to different spool design of 1kg spool filament and it can also hold up to 270mm diameter of spool. I have tested the design up to 9kg dumbbell torture test, therefore I think it may be able to adapt up to 3kg and 5kg filament spool.
