Reel-Cap-Storage

Am sure I'm likely not the first to think of this, but ...

When you run out of filament, don't throw away the Filament Spool, turn it into a handy storage device.

Each Spool can accommodate 4 drawers, meaning all those loose bits n bobs have somewhere to live where you can easily find them.

This is drawn for a 100mm diameter Reel, with a 50mm diameter centre. I would imagine, if your reel has different dimensions then resize x,y and z as needed and it should print fine for any size.
