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.
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.
