# Gridfinity Rebuilt in OpenSCAD 

A ground-up port (with a few extra features) of the stock gridfinity bins in OpenSCAD. Open to feedback, because I could not feasibly test all combinations of bins, so some of them may have issues. 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.

The printable holes allow your slicer to bridge the gap (using the technique shown [here](https://www.youtube.com/watch?v=W8FbHTcB05w)) so that supports are not needed.


## Recomendations
For best results, use a version of OpenSCAD with the fast-csg feature. As of writing, this feature is only implemented in the [development snapshots](https://openscad.org/downloads.html). To enable the feature, go to Edit > Preferences > Features > fast-csg. On my computer, this sped up rendering from 10 minutes down to a couple of seconds, even for comically large bins.  

## Enjoy!
