i3 (Pro W) 6mm Wood Frame Spool Holder

Just resized the bottom part of the holder as on the original one designed for Acrylic was too big (nothing that some some spare paper in the empty space can fix) for my i3 Pro W that have a wood frame

as it will work as is, my advice is to use it with some filament guide like this https://www.thingiverse.com/thing:1528628
