Yeah, that's kind of neat. Archive: https://archive.today/p7WXn From the post: >>Want to make your own ergonomic mouse but don’t know where to start? Why not try [psudoku]’s Kotinos design? It’s a scaffold-like fingertip shell that uses the internals of an HSK Pro mouse. Each fingertip gets its own little saddle-shaped nook, and things like hand size and paddle surface can all be configured by modifying the OpenSCAD scripts. [psudoku]’s unit looks to us as though it was maybe made using multi-jet fusion (MJF) 3D printing, but it should be perfectly printable on hobbyist printers, whether resin- or filament-based.
