I made this for my wife because I really wanted to use the bathroom sink area. The pieces snap together when held at a 90 degree angle from each other as shown in the last picture. Every other one should be rotated 180 degrees. I am including the blender file. You can see the history of how my design evolved if you know how to use blender. As with all my files, please do anything you like with this. All my designs are free for anyone to print for any reason. If your print seems to break in the same place let me know where. I hope you learn blender and modify my design and share it. I would recommend it to anyone.
