I designed this spice rack for my camper van to solve a common problem: how to keep spice jars secure and accessible, even when they are mounted upside down on a cabinet door th at opens upwards. This design holds the jars with a satisfying "snap" and keeps them firmly in place, even on bumpy roads.

The model is specifically designed around the popular and affordable IKEA CITRONHAJ and IKEA GULDFISK spice jars, but the best part is that it's fully parametric. By using the included .scad file in OpenSCAD (which is free software), you can easily customize it to fit any jar, change the number of holders, and fine-tune the fit to your exact needs.

 

Key Features

  •  Extremely Secure Hold
    The snap-fit design and tight tolerance grip the jars firmly. As you can see in the photos, they won't fall out even when mounted completely upside down.

  • Optional Bottom Support
    For extra peace of mind, especially in mobile applications like vans or RVs, you can enable an integrated bottom support structure that provides another point of contact.

  • Fully Parametric
    The OpenSCAD file lets you change everything! You can easily adjust the jar size, number of holders, grip tightness, and more.

How to Customize (Using the OpenSCAD file)

Download and open the .scad file in OpenSCAD. All the important settings are at the very top of the file.

  •    number_of_holders: Set the number of jars you want the rack to hold.

  •    jar_diameter: Measure your spice jar and enter its diameter here.

  •    tolerance: This is the key to the perfect fit! Use a negative value (e.g., -3) for a tighter snap-fit, or a positive value for a looser fit.

  •    add_bottom_support: Set to true to include the extra support arms, or false for a more minimal design.

  •    screw_hole_diameter: Adjust this to match the screws you plan to use.

Printing Instructions

I printed this successfully using the following settings:

  •    Material: PETG (Recommended for its strength and slight flexibility for the snap-fit).

  •    Nozzle Size: 0.4mm

  •    Layer Height: 0.28mm

  •    Perimeter: 4

  •    Supports: None needed.

  •    Orientation: Print the model lying flat on its back, with the hooks/clips pointing up. This provides the best layer adhesion and strength for the clips.

  •    Infill: 12-25% is sufficient.
