This is a simple mod adding three independent sliders to part menus, allowing you to scale or shrink parts along individual axes in editor. It is compatible with TweakScale Rescaled (respects part scale changed with TSR and vice versa) and (apparently) pretty much all part mods, including Procedural Parts and Procedural Wings. Stretched animated parts work fine. Waterfall plumes also roughly match the stretched engines' dimensions.
It was initially made as a tool for personal use in greebling and setpiece crafts, and so please note that this code was mostly written by Claude Opus 5.5. I reviewed it to the best of my abilities, but I'm a C++ programmer, not a C# one, and so I can't quite guarantee its flawlessness in good faith.
Changes made via StretchScale do not affect parts' stats or aero models like TweakScale does, only changing the visible model and its collision. This is a conscious choice made to keep the code as simple as possible and minimize possible points of failure.
Anyone more competent in C# is welcome to adopt it for further improvement. Source code is included in the download .zip.
