This is a simple honeycomb/hex insert that slides into a bucket.
I eat greek yoghurt. It comes in 2L buckets. I have a lot of empty buckets. Maybe one day they will become filament. Not today.

The photo shows a shorter version with thinner walls (batteries) that is superseded by the larger one (tools). If you want shorter then just cancel the print at that height.... or something. In theory my original model fills the entire height of the bucket, so I can upload taller ones if anyone cares.

Assembly:
Insert print into bucket.
Take a permanent marker and scribe it around the inside of the bucket to mark where the insert ends
Remove the insert
Cut the bucket (shine a light into the bucket so you can see the line, and your fingers. Two or three passes of a blade tip to mark a clean furrow, and a final pass to cut through exactly in the furrow works best)
Reinsert the insert
Clean up the small tools on your desk by putting them in the bucket sections.
Glory at the beauty of an object that floats like a small boat of organisation on the sea of chaos and small parts that is my workbench.
