Thin Spool Holder for Thing Version 2

Thin Spool Holder for Dry Filament Box (Thing 4056923) A few months ago I published a "Dry Filament Box" which is very useful to save filament from humidity while printing. Normally the box is fine to use with the given configuration, meaning four bearing balls and two axes carry the spool and provide the right friction. Sometimes you want much less friction, for example if you are using a direct extruder and a housing. So you need this small "addon" to the Box. The holder will be set to the former bearing ball cages flat side to outside. In the cones you have to insert the bearing balls from the box (only one each cone). Additionally you need a threaded rod M8 about 90..10mm long as the rotating axis. #Version 2 Now I finished the next generation of this thing. There are several improvements: -Cones are shortened, better matching to 700g...1000g spools with less "screw work". -Windings are improved too, less post-processing work to match. -Cones got holes for fingers for easier handling -Bearing-Ball seats are extended 0.5mm for better matching -The wall was split into a WallDeep and a Wall Flat. -Now walls will not tilt, they remain in position -Axis will now be hung simply into walls. Easier handling. #Version 3 (6. May 2021) I recognized that some spools don't fit in outer diameter, so I enlarged the Walls 5mm, matching spools but matching housing too. -5mm more space for spools with big diameter -Wallthickness doubled (more stability) for heavy spools
