A simple but effective knock box for coffee grounds. It's been in daily use for ~6 months without a problem.
There's a hollow on the bottom for placing weights if you want a heavier box -- embed some nuts and bolts in silicone sealant. I found this wasn't necessary though.
Dishwasher safe if you use a heat-resistant filament; I printed in polycarbonate and it goes through the dishwasher without issue. If you do this, it's worthwhile using silicone or epoxy to seal the bottom chamber so water doesn't pool there and enter the body.
Print with supports for the bottom hollow. 3 walls, low infill is fine.
