Modular spice rack

🧂 Modular Spice Rack System

This project is a fully modular and customizable spice rack, designed to fit neatly into your kitchen shelves and adapt to your jars.
The model is split into 4 print plates, each one providing the parts needed to expand your storage system in different ways:

📦 Plate 1 – Base Module

• 1 container with a sliding tray.
• The tray has a front handle and a stopper to prevent it from falling out.
• The tray slides into the container through two small openings that align with its rails.
• Includes caps for corner and side openings, allowing you to close unused connection points.

📦 Plate 2 – Stacking Module

• 1 container and 1 tray.
• 4 connector bars to stack this container on top of the base module (Plate 1).
• 2 covers for side openings.
• Note: corner caps are not included here (they should be reused from Plate 1).

📦 Plate 3 – Side Extension Module

• 1 container and 1 tray.
• 4 corner caps.
• 1 lateral joint to connect this module underneath the base module (Plate 1).
• Note: no cover is included for the other joint, as it can be reused from Plate 1 once this module is attached.

📦 Plate 4 – Stacked Side Extension

• 1 container and 1 tray.
• 1 lateral joint to connect on top of Plate 3 and alongside Plate 2.
• 2 double connector bars, designed to stabilize both upper and lower containers simultaneously.
• When using these double bars, 2 of the regular bars from Plate 2 must be removed and reused to secure Plate 4.

🔄 Expanding the System

• To add another stacked floor → print Plate 2.
• To add a side module → print Plate 3.
• To add a stacked side module → print Plate 4.
• You can print these plates as many times as needed to build the structure you want.

⚙️ Parametric Options

The current profiles are optimized for spice jars of 45 × 45 × 120 mm or 70x70x130 mm and a 235 mm deep shelf (also for 180 mm deep shelf as the maximum size for the A1 mini), but this design is fully customizable so you can adapt it to your own jars easily. Three main parameters control the entire system:

• Long → The full depth of the container (usually matching your shelf depth).
• JarDiameter → The diameter/width of your spice jars.
• JarTall → The height of your jars. This determines the height of connector bars when stacking containers.

⚠️ Important: if you combine containers with different heights, you cannot use the double bars from Plate 4. In that case, you’ll need to rely on the lateral joints only for stability and use the bars from Plate 2.

🦶 Adjustable Feet (New)
 

A new optional profile has been added to improve compatibility with different cabinet types.
 

This plate includes a set of feet with different heights (2 mm, 4 mm, 6 mm, 8 mm, and 10 mm), allowing you to slightly elevate the spice rack when needed.
 

This is especially useful if your cabinet has a front lip, uneven surfaces, or any obstruction that prevents the base from sitting flat or the tray from sliding freely.
 

By choosing the appropriate height, you can make the system more versatile and ensure smooth operation in a wider range of setups.


This model takes inspiration from the design by Rawsen Mitchell (https://makerworld.com/es/models/494987-modular-spice-rack), but has been entirely re-created from scratch in OpenSCAD.
