Bakugan Display Shelf

This is a storage/display shelf for Bakugan battle brawlers childrens toy. The shelf is designed to be wall mounted, the inner diameter for the screw hole is 3.5mm and the outer diameter is 7.0mm. The whole design is made to be modular so more shelves and main body can be added if more storage is needed. The notch on the back of the shelf is to indicate the side to be pressed into the grove on the main body. I haven't had a chance to print this design yet, so if you have any improvement suggestions please leave a comment. Thanks, and enjoy!!!
