Another spool case / Drawer !
Theses drawers fit a 200mm (Outer diameter) spool with an inner diameter of 106mm an 46.5mm wide (750g ICE filament).
There are four different sizes (180°,90°, 60° & 45°) with two different heights. You can either have one or two drawers for each section and you can mix section sizes.
The drawers turn around a pillar that you can glue or screw in place (I've used 3x10 Philips screws).
Fusion 360 file attached, feel free to use it !
Infill isn't really needed since it's mainly outer walls and top/bottom layers.
