About this 3D model

I designed this planter in the shape of a puzzlepiece for the TinkerCAD design competition. It does not only look like a puzzlepiece, but truly is one. If you print multiple of these planters (using the same scale), they should be able to fit together like a plant-y puzzle. Sadly, I do not have access to a 3D printer, so I am unable to print the planter to test the concept and figure out whether the pieces actually fit together, but if anyone can, please notify me if it works and whether any adjustments should be made. This object was made in Tinkercad. https://www.tinkercad.com/things/4Wo7WF6vy81
