Yet another filament spool holder

Here is another 1kg Filament spool holder for your 3D printer.

The spool holder is designed to make a very quick spool change.

I used 25% infill, but probably a lower value (15 - 20%) will work just as well

The final unit assembly requires 4 drops of Cyanoacrylate (Superglue) one in each corner where the left and right supports meet the front and rear base.
