This is a replacement "capsule container" aka coffee pod bucket for the Nespresso model Inissia "Original Espresso Machine", after aliens abducted our original bucket (or maybe the dog buried it in the garden).  The bucket base fits perfectly in the original Inissia drip-tray, and hangs over basin with about 20mm height-clearance so no need to worry about the 3d-printed part sitting in a puddle of coffee-water and getting disgusting.

Inspiration was this Thingiverse part, which wound up being way too feeble given the 1mm wall thickness.  If you're designing a 3d-printed replacement for injection-molded parts, don't be afraid of increasing the wall thicknesses!  The injection-molded part was presumably value-engineered to minimize material.  A chunky 3d-printed part will be easier to print and probably last longer.

Given the overhang, print with supports.  We discovered that darker filament covers are best--after a few months, the transluscent white PLA looked stained and foul.  The sparkly gray HTPLA from ProtoPasta has lasted for over a year.

I've included the very ugly Fusion CAD model so you can make edits.
