modular interlocking drawer dividers

You need a drawer divider for the cutlery tray in the kitchen? Or an organizing system for the desk drawer or the craft cupboard? Try this modular openSCAD design.

Here is my first use case: My son works as a bartender in a hotel and needed a divider for a refrigerator drawer to hold the various beverage bottles. The drawer was much larger than my print space. In addition, the compartment dividers should be easy to remove and clean in an industrial dishwasher. Thus I disassembled the room dividers into individual parts that can be plugged together and separated again. I think this concept can be easily adopted to used for other formats as well,  here is the result

Implementation

The parametric design lets you create parts of any size (length / width / height) and all needed shapes necessary for right-angled divisions:

There are two types of components: plugs and sockets, which must always alternate. Five basic shapes are available as elements:

• pieces with straight ends, 
• adapters with either two plugs or two sockets, 
• T-shapes, 
• L-shapes 
• cross-shapes

To make your own drawer partition, make a sketch like the image below, calculate the leg length of the components and enter them in the customizer of the openSCAD model. 

 Make sure that red and green (socket/female and plug/male) are always alternating

Here some photos of the resulting modules:

Requirements and restrictions

• install openSCAD, see https://openscad.org
• install the great BOSL library from here https://github.com/revarbat/BOSL as it is required by the scad code.
• run openSCAD and load the modularDrawerPartition.scad file
• Currently, the leg length of all T / L / + shapes have same length for simplicity. I you want to have different leg lengths, you need to modify the code.

Hints

• print one plug and one socket of the desired wall width
• Check if you can put them together and also separate them again
• if they are too tight, increase the gap parameter in the tuning section
