A ground-up port (with a few extra features) of the stock [gridfinity](https://www.youtube.com/watch?v=ra_9zU-mnl8) bins in OpenSCAD. Open to feedback, because I could not feasibly test all combinations of bins. I tried my best to exactly match the original gridfinity dimensions, but some of the geometry is slightly incorrect (mainly fillets). However, I think they are negligible differences, and will not appear in the printed model.

## Introduction
Gridfinity rebuilt aims to remake the brilliant Gridfinity project from [Zack Freedman](https://www.youtube.com/c/ZackFreedman/about) in a more robust and open-source way than the original Fusion 360 files. Many major CAD suites struggle with making parametric models constructed from linear patterns, due to changing fillet edges and seams. Thus, a pure mathematical approach using OpenSCAD can allow a single solution for all possible bin variants.

The project has expanded into more eccentric models that use modules from the original generator. This wiki aims to document these modules in great detail.
The project has expanded into more eccentric models that use modules from the original generator. This wiki aims to document these modules in great detail.
Models are generated subtractively. First, the solid bin and bases are constructed, and then the compartments and holes are removed. This allows for internal fillets that nearly match the originals. However, they are not exactly perfect. There are some fillets that are too small and too difficult to be worth implementing, as most printers do not have a high enough resolution for it to matter.

Most files will come ready-to-run, so parameters can be changed using OpenSCAD's built-in customizer window, and the bins will automatically generate. However, all modules are packed up nicely, so any module can be imported into other files or have more custom modifications beyond tweaking the parameters.

Generates stock bins, but with a twist: the bases are hollow. This is unable to be implemented directly into `gridfinity-rebuilt-bins` due to its surprisingly complex construction. It couldn't be a toggle without causing the structure of the script to fundamentally change (and become more complex) so it was moved to a separate file. Notably, there are some parameters missing, as they are incompatible with the lite variation. Additionally, the complex geometry means rendering is fairly slow, and currently causes many CSG errors.

# gridfinity-spiral-vase
Some assembly required!
Adaptation of Gridfinity bins to work with spiral vase mode, as to save filament and print time. A big drawback of using vase mode for Gridfinity bins was that they would be very flimsy, and would lack the features that make Gridfinity such a good organizational tool. The goal of this implementation was to maintain the design philosophy while working under the constraints of vase mode.

## Instructions
Normal Gridfinity is impossible to convert to vase mode due to the geometry of the bases, meaning most existing vase mode Gridfinity models are limited to 1x1 bins. How this script gets around the impossible is to use two separate pieces. **The bin and bases must be printed separately, and then glued together to form the final bin.** While this is slightly more work, there is an added bonus to this method, as for larger bins you may not need every single grid slot to have a base, you only really need them on the corners, or the edges, with some in the middle for support. Using less bases saves filament and print time.
All parameters are global. The customizer has descriptions for all parameters. It is **essential** that the section *Printer Settings* matches your preferred slicer's settings, otherwise the model will not slice correctly. Additionally, you have to turn on the spiral vase parameter in your slicer. If you do not know what vase mode is, [this](https://www.youtube.com/watch?v=HZSFoFYpBaA) is a helpful video.

1. Change the *Printer Settings* parameters to match your slicer and printer settings.
2. Run the `gridfinityVaseBase()` module. This will generate a single spiral-capable base. Export as an STL file. You will need to print multiple of these, so it recommended to fill a base plate with them using the "complete individual objects" option (or equivilant) in your slicer. You only need to do this step initially, and then each time your printer settings change afterwards.
3. Change the bin parameters and run `gridfinityVase()` module to generate the main bin.
4. Glue bases to the bottom of the bin. I recommend superglue on the corners and the top of the magnet holes.

Given how it has become a bit of a [challenge](https://www.printables.com/model/265271-gridfinity-lite-economical-plain-storage-bins) to reduce the weight and print time for these bins, here is a comparison for a large bin:
@ -32,7 +32,7 @@ Plain 4x2x6 Bin | 114.66g | 3h58m
Vase 4x2x6 Bin with 8 Bases | 68.31g | 2h27m
Vase 4x2x6 Bin with 4 Bases (only corners) | 56.43g | 1h59m
Clearly, vase mode is very quick and quite lightweight. However, this fundamentally means the bins will be weaker, so keep that in mind.

### gridfinityVaseBase
Generates the base section of the bin. No parameters as it uses the global parameters for construction. It only generates a single base, as all of them are the same. Use your slicer with the "outpuit individual objects" option to print a full sheet of these, or as many as you need to fit your bins.
