Modelo 3D Parametric Gridfinity Box+Drawer System (CadQuery) por dhch no Printables

Descrição

Almost everything is changeable via list of over 30 parameters at the beginning of the main script. The default settings are my preferred ones, which are optimised for least material-use and fastest printing, while still printing really solid out of PLA. All parameters are described in detail in the script. I can not guarantee that every possible parameter combination works, since i have only tested some combinations. Especially when going into extremes with some of the secondary dimensions, it might result in some unexpected outcomes.

There are many pre-generated models to choose from which all use the default parameters.

This is inspired by "Improved modular gridfinity drawers" by @PhilCraft. The main drawback by his design is, that every drawer has its own box. With my approach, the overall material usage for the boxes can be reduces by roughly 40% and can even be printed a lot faster when not using the hex-perforations, but instead the embossed cavities wall setting. The single boxes with hex-perforation setting are basically the same as the ones by PhilCraft.

The main script is "ParametricGridfinityGenerator.py" with all the parameters. This will generate and export only one model (can be chosen which). There are also some scripts "batch_export_XXX.py" which can be used for batch exporting many different models. The settings for each batch run are saved in a json file for further recreation.

When wanting to connect multiple boxes next to each other, there are connector wedged. Setting the CREATE_PARTS parameter to "wedge" generates those connectors. I recommend to print those out of TPU.

There are cutouts for 64x23mm paper labels in the frontplate of the drawers, which reduzes in size if the drawer gets too small.

Settings for the box:

basic size of the box and drawers (how many gridfinty units width, height, depth)
basic layout of the drawers (how many drawers per row, how wide each drawer, number of rows)
wall modifications to save on material and print time
- solid walls
- hex-perforation, which is slow to print but uses less material than solid walls
- embossed cavities (thin walls mostly with thicker surrounding walls), which is the fastest to print and uses the least material (faster than solid walls and less material than hex-perforation)
- can choose some dimensions for each kind of wall modification
- can choose which walls to modify
wall thickness of outer and inner walls
add an extra gridfinity baseplate on the top surface of the box
and some more, just look in the script

Settings for the drawers:

wall thickness (bottom and side seperate)
embossed cavities on the side walls to reduce material use
baseplate settings like magnets, screw holes
flat baseplate or with gridfinity pattern
and some more

If you want to modify something custom, claude is pretty good with cadquery scripts.

If you want some models with custom parameters, let me know in the comments and i will generate them for you, when i come around.

Naming convention for the exported multi boxes is "box_multi_DEPTH_FLOOR1_..._FLOORn", where FLOOR has the format of AhB-C-D..., where A is the height and B,C,D... is the width of the individual drawers.

EDIT 2026-05-31: added exported models of drawers with magnet holes only (no screw holes), so the floor of the drawers does not have any through holes (also easier to glue in the magnets this way)

EDIT 2026-06-29: added custom models folder; minor bug fix in main script when generating multi boxes with different wall thicknesses
