Modular Gridfinity Drawers

Lightweight & Fully Extensible

Gridfinity Drawer

for 

HomeRacker

📼 Watch This Video 

This is a fully customizable and extensible Gridfinity Drawer system for HomeRacker! It's designed to be lightweight and highly efficient for organizing small items like screws, hardware, and small tools.

The system is incredibly flexible: you can start as small as a 1x2 Grid and go up to a massive 10x10 using the Parametric Model Maker (PMM)! 

Get ready to organize your entire workspace. ✨

🛑 Usage Disclaimer & Weight Limit

⚠️ ATTENTION: This drawer is not for you if you need to store heavy equipment or large tools. It is optimized for light items only, maxing out at 2kg per drawer (e.g., screws, small components, hardware). Please distribute heavier loads across multiple drawers.

💡 Need a Heavy-Duty Version? Let me know in the comments! I already have a stronger model design in mind and your feedback helps me prioritize it!

✨Key Features

• Fully extensible drawers for easy placement and detachment of Gridfinity bins. ↔️
• Introduced safeties to prevent drawers from falling out. 🔒
• Stack and rack drawers infinitely in two dimensions thanks to HomeRacker. ⬆️
• Combine drawers with any other extension in the HomeRacker ecosystem, like Gridfinity Shelves. ➕
• Parametric design allows easy configuration by Gridfinity units in the PMM (Parametric Model Maker) or download the f3d file for advanced tinkering. ⚙️
• Customizer allows for drawer sizes from 1x2 up to 10x10 Gridfinity units. 📏
• Designed without the need for printing supports. ✅
• Front plates with a handle and detachable label plates that can be customized and scale with the drawer's width and height. 🎨

🖨️ How to Print & Assemble

Refer to the video above or the Printing & Assembly Guide in the documentation section.

Let's quickly cover the two most common issues you'll face with this design:

1. Warping (Your Biggest Enemy! 🥵)

The biggest enemy here is WARPING. Not only does it look bad, but it will severely disrupt—if not completely destroy—the functionality of the drawer slides. Filaments like ABS and ASA are notoriously challenging and can be "warping divas" on this design.

Be especially careful when you max out your printer's build plate (e.g., a 5x6 grid on an A1). Pushing the limits this way leaves zero margin for error, and prints become highly prone to warping on the outer edges.

2. Impatience (Cooling Time is Crucial! ⏳)

The second major pitfall is impatience. Peeling your prints off the build plate too early can easily deform the delicate drawer slides, permanently making them unusable.

You must let the parts cool completely for at least 30 minutes before attempting removal. After cooling, you can proceed with the final assembly (see the guide for details).

The Secrets Behind the Icons & Label Text! 🤫🛠️

Bonus: If you're wondering how these cool icons and label plates were created, this video details the "Slicer Trick" for adding graphics to 3D prints without needing CAD skills:

🐘 Load Bearing

The load capabilities are limited, but the design is resilient. Here's a visual test:

943g                                                                             1787g                                                                         2677g

These three pictures illustrate the bending progression of a single 5x6 drawer when overloaded. For this test, I simply combined the contents of three separate drawers onto one! As the final picture clearly shows: it bends heavily, but it will not snap thanks to the intelligent printing orientation. This demonstrates the drawer's resilience! 💪

Nevertheless, this model is not intended for heavy-duty applications. Please refrain from loading too much weight to maintain drawer integrity over time.

🏡 What is HomeRacker?

HomeRacker is a universal modular rack building system I created. It's based on an open specification. Find out more here:

HomeRacker - Core on Makerworld

or checkout

The Official HomeRacker Collection

With HomeRacker, you can build all sorts of things—like the Dry Filament Shelf or this 10" Cyberpunk-style rack which you can also find on Makerworld. Check it out!

What's in the Box??

Besides the customizable Fusion 360 file (find it via Download STL/CAD Files), there's also the showcase model as 3mf file, which contains the EXACT model shown in the profile picture.

A Note on Print Profiles: The attached print profiles are only examples! Their only purpose is to give you a small glimpse of what's possible. I designed HomeRacker so you can build basically ANY combination you fancy. Be creative! 💡

What's missing?

To build a custom drawer you'll need - besides the customizer results - additional connectors and supports, download the free HomeRacker - Core system. Please refer to the Assembly & Printing Guide in the Documentation section.

🤝Community Driven

I created HomeRacker - Core as an open specification. This means anyone can create and share their own extensions and models based on it without any licensing restrictions—all I ask for is attribution!

🧑💻 For Designers
