Based on great design from https://www.thingiverse.com/thing:3723481

• Changed round holes pattern on the sides to lines as these are easier to print and I find them nicer
• Increased screw hole holder height so very small screws can be used
• Created passive design with regular lines for those who don't like using infill paterns
• Added closed fan style (to be printed without top/bottom layer)
• Changed side cutout for bigger hdmi adapters
• Added sdcard cutout with classic square style

Has 4 types:

• Passive for those who don't want a fan - solid top (can be used without top/bottom layers) or top with regular open rectangles, has enough space for a heatsink
• 30mm fan support
• 40mm fan support
• 30mm or 40mm with a solid top (to be printed without top/bottom layer) which can be used to have the fan but still enclose it in the same nice pattern (picture 1)

Fans are held just by friction when they are inserted, they can be secured with a bit of glue although I don't think that will be needed.

Note: if you want this grid pattern print without top & bottom layers

• in Cura set those to 0, and then select infill Grid with 3.0 line distance or Lines with 28% density, or whatever you like
