Build Your Own Gridfinity Storage System

If your desk drawer is overflowing with screws, cables, and electronics, it’s time to try Gridfinity—a modular, 3D-printed storage system that’s fully customizable. This step-by-step guide will show you how to design, print, and assemble your own Gridfinity setup to organize your workspace like a pro.

All you need for Gridfinity is a 3D printer. If you do not have one, PCBWay can help you out with their 3D printing service that creates parts with outstanding quality.

Below are some of the tools I use in everyday work as well as some modules that I will be organizing with Gridfinity. These are affiliate links, so if you purchase through them, you support me and my channel, at no additional cost to you!

Start by measuring the dimensions of your drawer or workspace where you plan to install the Gridfinity system. Since the system is based on a 42x42mm grid, calculate how many of these units will fit in your space. This will help you determine the size of the base plates you’ll need to print.

You can also use a planner tool to help you visualize what you need: https://gridfinity-base-planner.vercel.app/

Next, use an online Gridfinity generator to create custom base plates and boxes. These tools let you choose features like label tabs, rounded edges, or internal dividers to suit your storage needs. Once you’ve customized your design, download the STL files so they’re ready for 3D printing.

Load the STL files into your 3D printer software and start printing the base plates and boxes. PLA filament is a great choice for beginners, but you can use any material you prefer.

Adjust your printer settings to avoid stringing and ensure smooth, high-quality prints.

Print a few test pieces to make sure everything fits together perfectly.

Once all the parts are printed, it’s time to assemble the grid.

Connect the base plates using 3D-printed connector clips.

If the clips feel too tight, consider printing them with a more flexible filament like TPU. Make sure the grid fits snugly in your drawer or workspace and is securely connected.

Now for the fun part—filling your Gridfinity system!

Place your items (screws, cables, microcontrollers, etc.) into the boxes. 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, and enjoy your newly organized space.

With your Gridfinity system complete, you’ll have a clutter-free workspace that’s both functional and customizable. For more tips and a detailed walkthrough, check out the full video tutorial.
