The module tray that comes with the deluxe version of Andromeda's Edge can't hold all the sleeved module cards. These deck holders are designed to fit the module cards sleeved with the sleeves that come with the All-in pledge and be slotted onto the module tray. Of course it can also be used by itself if you don't have the module tray.

You may need to turn on the "Detect thin walls" settings (or equivalent) to avoid the slicer making small holes in the bottom corner.
