StudioArk is a free in-browser design tool for 3D-printed dust covers that fit DJ and studio gear — CDJs, mixers, controllers, grooveboxes, synths and turntables. You give it your device's width, depth, corner radius and tallest control, and it exports a print-ready 3MF or STL. It generates geometry on your own machine, so it needs JavaScript, WebGL and WebAssembly to run.
