On the default installation the buffer of the CFS for the Creality Hi is held in place using double side tape.  That is a problem if the filament get tangled and you need to open the buffer.

With this adapter you can put the support to the printer using the double side tape and then attach the buffer using screws so you can take it and put it back without effort.

I used two bronze inserts as nuts for the screws, can be any of 3 mm or less thread,  for screws you need 2 units, 2.5  10 mm  or 3 mm  10 mm.
