@jacqueline @mntmn Right now, the bottom seems to be completely flat on the inside. This means that I'd probably glue or tape things to it to keep them in place. I wonder if the Next body should come with anything that helps in attaching new mods to the bottom (like some protrusions and holes for M2 screws or the like). Or whether having the bottom anything but plain flat would mainly hinder creativity... 🤔
