Stackable Blue-ray Disc stand

A simple and stackable storage for disc. I have a TV unit which has smaller vertical space and all available models were too big to fit in there. Parts are

1. Disc holder: The main container to put your discs.
2. Joining Bolt: For the lack of better words, used to join two disc holders on top of each other to fit firmly.
3. Base leg(Optional): Just a modified joining bolt which can be used to tilt the entire stand to make it more accessible. Attach 2 of these to the front of the bottom most disc holder 

Print the holder  the curved end resting with brims n support should be needed
