Introduction

Gridfium is a modular organization system built on a standard 25 mm grid.

Every object snaps to the same grid, so modules stay aligned when you combine them. Pick an object, configure it to fit your space, print it, and build a layout piece by piece.

Because sizes are expressed in grid units, pieces stay interchangeable: start with a base plate, add a tray, a cup, a divider, re-print a single module when your needs change — without redesigning the whole setup.

Gridfium aims to be a versatile system that can be used in a variety of spaces. Almost every object serves more than one purpose. MegaTrays work equally well for drawer interiors and cabinet shelves. Trays are perfect for kitchenware, stationery, and a wide variety of tools. Cups look great on desktops, in bathrooms — and also double as planters.

Measuring footprint

Get the dimensions of your space in millimeters — width (left to right) and depth (front to back). Measure at a few spots; drawers and shelves are rarely perfect rectangles, so use the smallest value for each dimension.

Divide each measurement by 25 and round down. That gives you the footprint in grid units.

Base plate

Base plates are the foundation of the system. They give modules a grid surface to snap into and keep everything aligned.

Connecting multiple plates

If your space is larger than the printer build plate, use several base plates and connect them.

Each edge of a base plate — front, back, left, and right — can have a Male or a Female connector. Just like in jigsaw puzzles.

Male connectors are tabs that protrude from the edge; female connectors are matching slots that receive them. To join two plates, set a male connector on one edge and a female connector on the matching edge of the adjacent plate. The plates lock together and stay aligned on the grid.

Rounded corners

Rounded corners add a finishing touch to exterior compositions.

For example, if building a desktop or bathroom organizer, you can choose a single base plate with rounded corners and no connectors.

For larger compositions, you can combine rounded corners and connectors to get the exact configuration you need.

Choosing objects

Gridfium objects are designed to mix freely on the same grid. Start from the space you are organizing, then pick the modules that fit the job.

Kitchen drawers

• Sidecut Trays — tea spoons, cocktail umbrellas, measuring spoons, napkins
• Channel Dividers — parallel rows for spoons, forks, knives, and chopsticks
• Corner Dividers — spatulas, ladles, and other larger utensils

Desk drawers

• Sidecut Trays — pens, pencils, rulers, and neatly folded cables
• Channel Dividers — pens, rulers, and other long items in parallel rows

Desktop

• Tall cups — pens, pencils, rulers, brushes and other creative supplies
• Sidecut Trays — writing pads
• Short Cups — catchall trays, paperclips, coins and other pocket-sized items

Bathroom

• Tall Cups — toothbrushes, razors, and cosmetics
• Short Cups — cotton pads, tubes, and small toiletries

Workshop

• MegaTrays — nuts, bolts, bearings, screws, fasteners and other workshop supplies
• Crates — parts, shop supplies, and anything that needs a simple stackable container for longer-term storage
• Sidecut Trays — wrenches, pliers, brushes, screwdrivers and other long-handled tools
• Tall Cups — screwdrivers, pliers, files and other long-handled tools
• Short Cups — catchall trays for small items

Electronics

• MegaTrays with MegaTray Dividers — PCBs, modules, connectors, and small components in sorted compartments
• Battery Holders — AA and AAA cells in compact layouts
• Bins and Crates — wires, breadboard parts, and loose hardware

Plants

• Cups and Cup Inserts — modular planters for windowsills
• Base Plates with solid bottom double as drip trays under pots

Completing a layout

• Spacers and Placeholders — fill gaps between dividers or unused grid cells for a tight fit
• Adapter Plates — stack smaller modules on larger ones for multi-level storage

Print settings

All Gridfium models are designed to print as easily as possible on mainstream FDM printers.

• Nozzle: 0.4 mm (standard)
• Layer height: 0.20 mm or 0.16 mm
• Arachne wall algorithm is recommended for labels for more accurate results.
• Infill: no special requirements — use lighter infill for faster prints or heavier infill if you want more rigidity
• Supports: none required
• Material: PLA or PETG both work well. Personally we find PLA easier to print and sligtly more rigid, whereas PETG is a bit more durable.

Your slicer's default profiles for these settings should produce good results. If a first print feels too tight or too loose on the grid, small adjustments to flow or horizontal expansion in your slicer usually fix it.
