No support needed.

It fits 73,5mm diameter spools, such as SUNLU and Anycubic spools (according to my tests on the brands I have with a large diameter spool).

NOTE: Some spools have a draft (a slight taper) on the inner diameter walls (usually on the part with the filament tag on it).
If you find that the adapter does not fit well when you insert it, do not force it and try inserting it on the other side of the spool.

To remove it from your spool, just push with 2 thumbs on the opposite side and it should pop out without any problem or too much pressure (even though the area for your thumbs is quite small, don't worry, you will still be able to grab the extremity of the adapter).
