HELIX - Sink Tray 02 - Kitchen Sponge Caddy

Overview

Sink Tray 02 is part of the HELIX collection within Engineered Modern — a series of surface-focused objects designed for wet environments.

The goal is not novelty, but refinement: controlled drainage, improved airflow, and deliberate geometry.

System Context

HELIX explores how objects interact with surface, gravity, and contact in water-adjacent spaces.

Each piece in the collection prioritizes:

• Intentional slope

• Reduced water retention

• Elevated contact surfaces

• Clean internal geometry

• Stable countertop interaction

Key Design Decisions

• 5° Drainage Plane
The base surface is intentionally sloped to reduce standing water and encourage runoff toward the sink.

• Elevated Rib Geometry
Ribs lift cleaning tools off the base surface to improve airflow and underside drying.

• Generous Internal Radii
Blends were sized for wipe-down cleaning and to minimize residue accumulation.

• Recessed Silicone Foot Pockets
Shallow underside pockets accept adhesive silicone pads for friction and countertop protection without increasing stack height.

• Expanded Footprint (9" × 5")
Sized to accommodate sponge, scrubber, and brush without crowding.

Intended Placement

Optimized for undermount sinks with flush countertops, allowing slight overhang so runoff returns to the basin.

Print Recommendations

• Material: PETG recommended

• Layer height: 0.20–0.24 mm

• Walls: 2–4 perimeters

• Infill: 15–20%

• Orientation: Base flat on build plate

• Supports: Not required if you choose “Support critical regions only” from the Advanced Support menu. Otherwise the foot pockets will get supports.

Files Included

• 3MF

• STL

• STEP (for modification or scaling)
