Pasta Lite Donor 3/5kg adapter

I used the filament spool holder from @d.lopeztin  to respool my 5 kg spool with the help of Pasta Lite.
Unfortunately, you have to hold both at the same time, and I just don’t have enough hands.
So I quickly designed an adapter that can be attached to the holder and connected to the Pasta Lite.
This makes respooling a breeze.
