Raspberry Pi 4 Case for Pi & Buck Converter - 50mm fan

thingiverse

As i found the [Raspberry 4 case ](https://www.thingiverse.com/thing:3811421) from user Tronnic, i was happy about the design. It was nearly perfect, but i had to make some little modifications: * Mounting posts more stable. * Raspi mountable with M2 screws or 2.2x6.5mm tapping-screws (no drilling of the raspi neccessary) * Cut-outs for USB-3C and HDMI expanded about 0.2mm in all directions. * Cut-out for USB-3 aligned with USB-2 (size and position). * Rounded corners (only for my eyes) Because i hate noise and i think its better to cool also the buck-converter (heatsink is here also important!) i made this additional modifications: * Case is 10mm higher. (for mounting a 50x20mm 12V fan) * Alternate lid for fan with 50mm. I use a 12V fan. Driven on 5V it makes enough pressure for cooling at very low noise level) * Lid with hole for 16mm button (shutdown)
