I had to turn on Brim, and add a support block using the Cura Custom Support Plugin (see photo), and turn on support brim as well to print this without it falling over. You may be able to get away with using a raft, just make sure the part is attached really well to the raft, or it will tip. I haven't tried this myself, though.
I made these quick display racks to use in my shop for displaying handheld games that don't have their cases. It works well for Switch, DS, and 3DS games and has a small ridge that keeps them from flipping back too easily. Use the "front lip" file if you're just printing one rack. If you want to make multiple rows of these, print the other file and tape/glue it to the back of the "front lip" file. The rack is 165mm wide, the width of 5 DS games.
I've successfully printed these at .3mm layer height, 60mm/s though they were a bit stringy. I just cleaned them up a bit because ideally, they're covered in games anyway!
