I suggest printing in highest quality and flip the bigger case upside down for less supports

you can just print the slide in like how it is

There are 6 cases the following are

-A case with a 30x30mm fan hole to slide into good for active/not active cooling systems. with and without logo

-A case with just a grate on top to help bring in more air good for active cooling systems. With and without logo

-A case with no hole just a solid case. With and without logo
