Gridfinity Eco Bin - all sizes

Gridfinity Eco Bin - Gridfinity Master Collection

I created this collection to facilitate easy and quick printing of eco Gridfinity bins. Each bin has its own named print plate, making selection of the correct size quick and easy. This collection includes all bins that fit on the 256mmx256mm build plate of a bambulab printer.

The bins are designed to be compatible with any gridfinity system while being as efficient as possible. 
 

When compared to the simple bin the eco bins save about 40% filament and 45% print time, with increasing savings with bin sized (better grid to wall ratio). The way this is mostly achieved is by hollowing out the base leading to an imprint of the grid on the inside. Another small upside is the slightly increased storage capacity in the height dimension. The major downside is the less clean look and the uneven height. 
The default print profile doesn’t require brims for adhesion.

 

Usage is pretty simple: Select the build plate with the bin size you want from the overview and send it to the printer. Ideal for beginners or a quick print job from the mobile app. 
 

The bins in this collection have a height of 2 HE to 12 HE with 6HE being the default height of gridfinity bins.
This creates bins that are 46mm high with an inner depth of 40mm on grid and 45mm of grid (35mm if you want to stack them). An increase of 1mm/6mm from the simple version.
Stacked bins are ~5mm shorter in total than the single bins

Other print profiles with different heights from 2HE to 12HE are also available in this model
 

Units	Outside	Inside max	Inside min	Stackable
2HE	18mm	17mm	12mm	7mm
3HE	25mm	24mm	19mm	14mm
4HE	32mm	31mm	26mm	21mm
5HE	39mm	38mm	33mm	27mm
6HE	46mm	45mm	40mm	35mm
7HE	60mm	59mm	54mm	49mm
8HE	67mm	66mm	61mm	56mm
10HE	74mm	73mm	68mm	63mm
12HE	88mm	87mm	82mm	78mm

The formula for the height is:
Outside: HE x 7mm + 4mm
Inside max: HE x 7mm + 3mm
Inside min: HE x 7mm – 2mm
Stackable: HE x 7mm – 7mm

Total height of stacked is 5mm less than the individual heights.

 

 

Comparrision to simple bin:

Using this Eco bin increases the inside depth by 1mm / 6mm when compared to the simple bin.
At the same time the hollow base results in roughly 40% of filament savings and 45% print time savings.
I highly reccomend using eco bins for first tests or when they are completely filled up with something. However the Eco Bins lack the clean look of the simple bins and (in this version) can't be secured to the base using magnets.

Other Gridfinity collections:

I have created other collection modells with the same alignment for easy and quick printing fully compatible with Gridfinity.

The Gridfinity project:

The Gridfinity system is a smart and flexible way to organize your space. Using a 42mm grid-based design, it lets you arrange different-sized bins and trays to store items neatly and efficiently. Whether it's for tools, office supplies, or household items, Gridfinity helps reduce clutter and keeps everything in its place. It's easy to customize and expand, so you can adjust it to fit your changing needs, making it a great solution for keeping any space tidy and organized. Gridfinity has a significant part in my decision to get a 3D printer.
Gridfintity was originally designed by Zack Freeman as an open source and free storage solution:

FreeCAD:

I created all the 3d files here myself with the free (LGPL) Gridfinity workbench for FreeCAD by Stu142
https://github.com/Stu142/FreeCAD-Gridfinity-Workbench

I can highly recommend this tool for generating bins that are tailor made for your application. The possible combinations of Gridfinity are nearly endless. After you have all your basic bins this is a great tool

Disclaimers:

I did neither invent Gridfinity nor parts of it, nor do I claim any ownership of this project.
I just created all the bins in this collection (324 so far and counting) to ensure the same parameters are used and organized them in an easy to manage and print manner. I created this collection to make it easy for myself and others to quickly send a bin request to a printer. It has proven practical for me to quickly request missing bins without having to browse through huge archive folders. 
If you think I somehow still stole the fame of Gridfinity I want to quote Zack freeman himself (video at 6:25): “It is a framework for the community…”

 

Other Notes:

Some bins appear to be duplicates. A 2x3 bin and a 3x2 bin have identical dimensions. I included both not only to satisfy my OCD but also for a practical reason. The bins are oriented differently on the build plate. This is very useful if the build plate is damaged at an edge or has a non-stick zone there (eg. touched by bare fingers to remove a previous print). Also it helps if you want to quickly print a bin at 3am and your brain can’t handle the task of recognizing that a 3x5 is the same as a 5x3…

The 6x6 bins are included in the STL file, but are not in the m3f for bamboo studio. These can’t be printed with the default Bambulab printers, since they have an exclusion zone for the filament cutter…
