This is a gridfinity bin, based on gridfinity rebuilt, for Wera L keys.

The bin is stackable by default.

It also has an angled recess so that the L keys stay in place even if there is some shaking. The top of each key is recessed 4mm into the bin, and the bottom 1mm. This ensures the keys are still easy to grab, even if the resulting shallow draft angles look a bit ugly.

Finally, the 90° angle is designed to accept a wide range of bend radii. Other models only accept a specific bend radius, so if there is variation between keys or the author didn't measure it properly, keys might not fit perfectly.

All these details lead to a somewhat uglier bin (compare 3rd picture), but make the bin more functional.

If you want to customize settings, such as the bin details or the angle of the keys, the openscad source is available on GitHub. There is also an online generator if you don't want to run openscad manually.
