Modular Parametric Drawer Divider (3D Printable)

A parametric drawer divider system designed for 3D printing, with support for large drawers through modular splitting and dovetail connectors.

This is a heavily modified version of the original customiser by ToM Krickl, adapted from their laser cut variant to 3D print-compatible variant, allowing for different bed size limitations with dovetail connector support.

Typical use cases

• Organising socks or underwear in bedroom drawers/cupboards/wardrobes
• Kitchen drawers for cutlery, utensils, or spice jars
• Office drawers for stationery, cables, or small accessories
• Workshop storage for screws, bits, and other small parts
• Bathroom drawers for makeup and toiletries

Because everything is parametric, you can quickly generate different layouts for different drawers without redesigning anything from scratch.

Features

• Fully customisable drawer size and divider layout
• Choose between a fixed number of compartments or a fixed compartment size
• Automatically splits large parts to fit your print bed
• Dovetail connectors for assembling split pieces
• Connector placement avoids weak areas near slot cutouts
• Designed specifically for 3D printing rather than laser cutting

How to use

Click Customize, enter your drawer dimensions, and choose how you want the layout defined.

If your drawer is larger than your print bed, the model will automatically split into multiple interlocking pieces. Be mindful that you specify the longer side with the most number of insert slots.

Saving filament 

To save filament, you can print the main divider bodies with 0 top and bottom layers and use sparse infill (e.g. honeycomb).

To reinforce the connector areas:

1. Import your generated STL into your slicer
2. Add modifier parts (e.g. cubes)
3. Position and scale them so they fully cover each male and female dovetail, including a bit of the surrounding base material
4. Apply the following settings to the modifier parts:
   • Top shell layers: 5
   • Bottom shell layers: 3
   • Wall loops: 2-4

Each model instance requires its own modifiers (they are object-specific in the slicer).

An example setup is included in the uploaded 3MF.

Parameter notes

Most settings are already explained in the customiser, but a few worth highlighting:

• drawer width / depth
  Internal usable size of your drawer. Measure carefully for best fit. I knocked 5mm or so to get it in my cupboard past the drawer (the model is flexible enough)
• divider height
  Height of the divider walls. Lower values reduce print time and material.
• material thickness
  Thickness of the divider walls. Around 3–4 mm works well for most uses.
• slot clearance
  Helps parts slide together.
  0.2 mm is a good starting point, adjust if fit is too tight or loose.
• print bed size
  Used to determine when parts need to be split.
• enable modular
  Enables automatic splitting for large parts.
• dovetail settings
  Control connector size and strength. Defaults are a good starting point.
• fixed number vs fixed size
  • Fixed number: evenly divides the drawer into a grid
  • Fixed size: repeats compartments of a chosen size
• all parts
  • Just major parts: one horizontal + one vertical divider
  • All parts: full set generated automatically

Print notes

• I've only tested this in PLA but I assume PETG would work well too
• 0.2 mm clearance worked well for my A1
• Dovetails are designed as a snug press fit, shouldn't need glue but it also wouldn't hurt
• For filament savings, combine 0 shell settings on the main body with reinforced modifier regions as described above
