Yet Another Raspberry Pi Case (YARPiC) Customizable

thingiverse

It appears that this is a changelog for an OpenSCAD design project called YARPiC (YARPi Case), which is designed for the Raspberry Pi 4 computer. The document outlines various updates and changes made to the design over time. Here's a breakdown of the main points: **Early Updates** * Added options for fan size, GPIO pin headers, and improved airflow (~6.5% better cooling) * Smaller power port when Pi4 is set to "No" * Deeper screw holes on the bottom * Modified top mounts to make them stronger * Added screw hole test **Later Updates** * Rewrote top code for performance improvement (later removed due to messiness) * Fixed bug with standoffs breaking * Removed reliance on third-party bevel library for beveled edge option * Fewer, larger cooling slots on the back * Embedded screw holes without supports * Added cutout for easier Pi4 insertion and removal **Recent Updates** * Made design compatible with OpenSCAD 2019.05's Customizer feature * Included pre-configured YARPiC designs in a .json file * Tidied up code for faster render times (~38% faster) * Fixed bug with fan mesh sticking out of the case when "gpio" and "fan" are set to "yes" * Prevented rendering of screwtest or dc_text with the case **Final Update** * Changed V/T-slot design to require two M3 T-nuts and two M3x8 bolts for added strength * Reduced default fragment number ($fn) from 50 to 24, halving render times without significantly affecting detail. Overall, this document provides a clear and detailed history of changes made to the YARPiC design over time.
