What is Gridfinity?
Gridfinity is an open-source, customizable storage solution designed to fit your exact needs. Built on a 42x42mm grid system, it allows you to create and combine base plates and boxes in endless configurations. Whether you’re organizing screws, microcontrollers, or tools, Gridfinity’s scalability and flexibility make it perfect for anyone looking to declutter their desk.
Main Components of Gridfinity
The Gridfinity system is built around two key components: base plates and modular boxes. Together, they create a highly customizable and scalable storage solution that can adapt to your specific needs. Here’s a breakdown of each part:
Base Plates
- These are the foundation of the Gridfinity system. Base plates are flat, grid-like panels with a series of 42x42mm squares that serve as slots for the modular boxes.
- They are designed to fit seamlessly into drawers, shelves, or any flat surface.
- Base plates can be connected using 3D-printed connector clips, allowing you to expand the system to cover larger areas.
Modular Boxes
- These are the customizable containers that sit on top of the base plates. They come in various sizes, shapes, and heights to store different items like screws, cables, microcontrollers, or tools.
- Boxes can be designed with features like label tabs, rounded edges, or internal dividers for better organization.
- They are built in multiples of 7mm in height, so you can stack them vertically to maximize space.
Together, these components create a flexible and modular system that lets you design a storage solution tailored to your workspace.
Getting Started with Gridfinity
To build your own Gridfinity system, you’ll need a few basic tools and materials. First, you’ll need a 3D printer and some filament (PLA is a great choice for beginners). Next, you’ll need access to design files for the base plates and boxes. The good news is that Gridfinity is open-source, so there are plenty of free resources available online.
One of the best ways to create custom designs is by using online generators. These tools allow you to input your specific dimensions and preferences, such as box size, height, and features like label tabs or rounded edges. Below are some examples that let you choose between different styles, like boxes with efficient floors (which use less filament) or ones with internal dividers for better organization.
When choosing box styles, think about what you’ll be storing. For example:
- Label tabs are great for quickly identifying contents.
- Rounded bottom edges make it easier to grab small items like screws or batteries.
- Efficient floors save filament and are ideal for lightweight items.
With these tools and tips, you’ll be ready to design and print a Gridfinity system that’s perfectly tailored to your needs.
Step-by-Step Guide to Building Your Gridfinity System
Building your own Gridfinity system is easier than you might think. Here’s a simple step-by-step guide to help you get started:
Step 1: Measure Your Drawer or Workspace
- Start by measuring the dimensions of your drawer or workspace where you plan to install the Gridfinity system.
- Calculate how many 42x42mm grid units will fit in the space to determine the size of your base plates.
Step 2: Use Online Generators to Design and Download STL Files
- Head to an online Gridfinity generator (links in the resources section).
- Input your desired box sizes, heights, and features (e.g., label tabs, rounded edges).
- Download the STL files for your base plates and boxes.
Step 3: 3D Print Base Plates and Boxes
- Load the STL files into your 3D printer software and start printing.
- Use quality filament and adjust settings like temperature and retraction to avoid stringing.
- Print a few test pieces to ensure everything fits together properly.
Step 4: Assemble the Grid Using Connector Pieces
- Once printed, connect the base plates using 3D-printed connector clips.
- If the clips are too tight, consider printing them with a more flexible filament like TPU.
- Ensure the grid is secure and fits snugly in your drawer or workspace.
Step 5: Organize Your Items into the Boxes and Label Them
- Start filling the boxes with your items—screws, cables, microcontrollers, etc.
- Use label tabs or adhesive labels to mark each box for easy identification.
- Arrange the boxes on the grid in a way that makes sense for your workflow.
By following these steps, you’ll have a fully functional Gridfinity system that keeps your workspace organized and efficient.
