Raspberry PI 4 case (fan or passive)

thingiverse

Based on great design from https://www.thingiverse.com/thing:3723481 * Modified round holes pattern on sides to lines for easier printing and a nicer appearance * Increased screw holder height to accommodate very small screws * Designed passive model with regular lines for those who prefer not to use infill patterns * Added closed fan design, printable without top or bottom layer * Altered side cutout for larger HDMI adapters * Included sdcard cutout in classic square style It comes in four types: * Passive for users who don't want a fan - solid top, printable without top/bottom layers, or top with regular open rectangles, with enough space for a heatsink * 30mm fan support * 40mm fan support * 30mm or 40mm with a solid top, printable without top/bottom layer, which can be used to have the fan while still enclosing it in the same nice pattern Fans are held in place solely by friction when inserted, but can be secured with a bit of glue if needed. Note: To print this grid pattern without top and bottom layers, - In Cura, set those to 0, then select infill Grid with 3.0 line distance or Lines with 28% density, or any other preference
