Parametric Wavy Tray – Elevated Drip-Drying Stand for Wet Items

A minimalist and elegant tray designed to let wet items dry efficiently — whether it’s a bar of soap, an oil bottle, a kitchen sponge, or a safety razor.

The tray features a sleek rectangular shape with rounded corners and a series of wavy internal ridges that keep objects elevated. These ridges follow smooth sinusoidal curves, spaced regularly and raised from the bottom. The thin walls promote natural air circulation and drainage, helping objects dry faster and stay clean.

What makes this model stand out is its fully parametric design:

✔ Adjust the tray dimensions

✔ Customize wave height, thickness, spacing, amplitude, wavelength or angle

✔ All parameters are editable in OpenSCAD with just a few intuitive variables

This makes it ideal for a wide range of applications — from bathroom storage to kitchen use.

Customization Instructions

Open the .scad file in OpenSCAD and modify the clearly labeled variables at the top to suit your use case. You can:

• Change tray dimensions (length, width, height) • Adjust the wave shape (amplitude, spacing, thickness, wavelength, angle) • Control the rendering precision (step_size, $fn)

Use it as a drying tray, soap dish, or multi-use platform — everything is tweakable to your liking.

Design once, remix forever ✨
