I was looking for a case to hold a few of my switch games for easy travel, but couldn't find any that I liked, so I made this one. Holds 4 games only, but it's a pretty easy print. For the shell, I printed it vertically so there were no bridges or supports needed. For the logo, I ended up printing it out separately and gluing it onto the shell. (If you have AMS you can just put them ontop of one another and print it, relatively easier.)
Note that there is a tab on one edge of each compartment on the case that works as a friction fit snap feature. Push the side of the game cartridge against that tab and pivot it into position to lock it into the case.
