Gridfinity Eco Bin - Gridfinity Master Collection

Sometimes the grid just does not match the targeted use, for example a drawer and there is a lot of wasted space. Or you want to put an eaven number of equal sized bins in an odd number of grid elements. Here come bins with a half step at the end in handy. Note that the tall (10HE and 12HE) 0.5 size bins might fall over if no neighboring bins keep them upright. But they print fine on Bambulab PEI plates.

There is also the Gridfinity Eco Bin, two side half grid - all sizes

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.

I created this collection to facilitate easy and quick printing of single (simple) 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.

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 the default print profile model have a height of 6HE – the default height of Gridfinity bins.
This creates bins that are 46mm high with an inner depth of 39mm (34mm if you want to stack them).
Be aware that the base grid also adds another 2-5mm - depending on the grid style.
Stacked bins are ~5mm shorter in total than the single bins

The grid size of the bins is in the 42mm grid of Gridfinity. Meaning all bins outside dimensions are a multiple of 42mm
For the inside dimension you have to deduct 2mm per side.
For example a 1x1.5 bin has 38mm x 59mm capacity, a 5.5x6 bin has 227mm x 248mm.

Other collections with different heights from 2HE to 12HE are also available as different print profiles:
 

The formula for the height is:
Outside: HE x 7mm + 4mm
Inside: HE x 7mm – 3mm
Stackable: HE x 7mm – 8mm

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

Other Gridfinity collections:

I have created other collection modells with the same alignment for easy and quick printing fully compatible with Gridfinity.
Alternitively there is the Gridfinity Simple Base Grid - all Sizes
and ofcourse the fitting Gridfinity Simple Base, half grid - all Sizes
There is the Gridfinity Simple Bin - all sizes
And the Gridfinity Simple Bin, half grid - all sizes
As well as the Gridfinity Eco Bin, two sided half grid - all sizes
A special Gridfinity Split Bin -all sizes allows to extend the length up to 11 units!
There is also the Gridfinity Eco Bin - all sizes for ~ 40% filament and print time saving. (sorry no split version, it is not sturdy enough)

Also there is the Gridfinity Label Bin - all sizes
Lastely there are the Gridfinity Lids / Blanks - all sizes

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](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 (288 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…”
