It's an adaption of the PS5/PS5 printable rack from Jack, since I really liked it and wanted to make it work for my other games.

Just print the bottom and top and add as much “stack parts” as you wish to create the needed space for your games.

Update 19.11.2024: I updated the width of the top and bottom plate, so that the fit for the games is way better (as shown in the new pictures).
If you already printed it, you just need to print the top and bottom piece again.
