I have included the fusion 360 file and have filled it with user controllable parameters. You can adjust not only the size of the box but how many rows and columns you have and you can make the divider go in straight or set them at an angle like I have done. It is all controllable in the parameters.

As a Tea tray, it can be used in a horizontal position which makes it useful for a drawer but it can also be used in a vertical position if you want to use it on the countertop without taking up too much room.

There are three different dividers. Two of them have tabs and one of them does not. The tabs are in case you want to add a label. Tab size is also a controllable parameter if you want to make it bigger. For the ones with tabs, you will need to print the one appropriate for your intended orientation, either vertical or horizontal. Technically either of them will work in either orientation but to get the nicest final look you really should use the correct part.

If you don't need tabs then print the third one. Not that this one has an arrow on it. Please install with the arrow facing the bottom of the box and with the arrow side facing you if using the box in a horizontal orientation or facing downwards if using in a vertical orientation. When installed correctly it should be flush with the top of the box.
