Pokémon ETB Divider

I use empty Pokémon Elite Trainer Boxes for storage/sorting and needed a way to divide them up so I can have more spots.

After printing in PETG this part is 75mm wide which sits nicely on the bottom of an ETB but isn't tight. The legs are 59mm long, which allows three of these parts to sit in an ETB and divide it into 4 spaces.
