Economical Gridfinity bins with scoop - vase mode

I'm working on a parametric version of this, when that is finished I will link it here. Currently I have uploaded some basic sizes. 

There are some other lightweight Gridfinity bin designs out there, but they don't have all the features I wanted. So I made my own. I've taken some inspiration from this design, but my design is very different.

What I wanted to achieve with this design.

• Economical, minimal filament usage and quick prints.
• Easy to use, I wanted a scoop, just like normal Gridfinity bins have. When picking up a part, it shouldn't catch behind the stackable lip, which was a problem I had with other lightweight designs.
• Strong, although it uses very little filament it should still be able to support bins filled with heavy hardware. I've tested this, and a PLA 1*1*3u bin can comfortably support 4kg. I haven't tested any heavier but I would be surprised if you needed a single bin to support more then 4kg.

To decrease print time this is designed for vase mode, your nozzle size and line width will determine the wall thickness, and therefore make a big difference in strength. I printed mine with a 0.5 mm nozzle and 0.6 mm line width. A 0.4mm nozzle is also able of a 0.6mm line width so should be able to produce a bin of the same strength.

In the slicer preview, the ribs should have two lines that are (almost) touching each other, if there is a big void, your line width is too small. 
The divider can have a small gap in between the lines.

Bottom thickness should be set to 1mm.

If you don't know about Gridfinity, it's an amazing system created by Zack Freedman. More info in this video.
