Tech tiles holder for the boardgame SETI - closed front corner

The tile holder for the technology tiles of the board game SETI: a search for extraterrestrial Intelligence by user Stoniac was a great idea and helps speeding up set up of the game.
I did notice that my tile stacks kept sliding out of the holder so I added a small extra wall in one of the front corners so the tiles stay in place without losing functionality.

I also added the original tile holder box by Stoniac. I didn't make any adjustments to this file but this way you can download the whole package in one.

I printed this without top and bottom layers (speeds up printing time, saves filament and stays sturdy enough) so that's why you see the inside of the walls on the picture.
