These are buckets for the honeycomb storage wall (There is also a square version.) Just print the bucket with the same size holder. BTW the render was my first in FreeCAD so dont judge me.
My recommended print settings:
* 0.4mm nozzle
* 3 walls
* 0.2mm layer height
* 20% infill
* 200 mm/s
* supports: You should activate supports for the holders. For the buckets it is not necessary but could help.
I also made some other versions. Check them out before printing. You might like them better: HSW removable Buckets/Boxes (round), HSW removable Buckets/Boxes (square).
Happy printing!
