Sink Drip Tray - Parametric

A sink-edge tray for sponges, soap bars and scrubbers. The ribbed floor drains straight back into the sink, and five parameters let you size it to your own sink.

What you get

• Ribbed floor: the item rests on the rib tips, so water runs off underneath instead of pooling

• Floor angled toward the sink with a front lip that hangs over the rim — water leaves into the sink, not onto the counter

• Open front and open top for fast drying and easy wiping

• One printed part, no fasteners and no adhesive — it just sits on the sink edge

• Print two or three at different widths and line them up along the edge, as in the photos

Fit check

• Sample files as supplied: 120 mm inner width, 67 mm deep, 48 mm high — measure your sink edge before printing

• Sample part as printed: 124.8 x 88.9 x 66.7 mm, with the drip lip hanging 18.7 mm below the tray floor

• Measure two things on your sink: flat edge depth (sets Depth) and run along the edge (sets Width)

• Every photo is the actual printed part in PLA on a real kitchen sink, no renders

Print settings

Bambu Lab P1S with a 0.4 mm nozzle, stock 0.20mm Standard profile.

• PLA (Bambu PLA Matte on the test print); PETG if it will sit in constant hot splash

• 0.20 mm layers / 2 walls / 15% infill

• Supports: yes, normal (auto) — the drip lip overhangs, and the bundled 3mf already has them switched on

• Width — inner width of the tray (120 mm on the sample)

• Depth — front-to-back depth (67 mm)

• Height — tray height above the sink edge (48 mm)

• Drip_Angle — slope of the ribbed drip floor (60 deg)

• Drip_Length — length of the drip ribs (15 mm)
