Rather than multiplexing filament through a single hot end, the design allows parking one hot end and picking up another. The project covers various failures and dead ends encountered during development. While tight tolerances may cause wear over time, the system works and could be adapted for homebrew printers or expandable platforms like the Voron. Previous homebrew tool changer projects are also referenced. ## Full article daily.dev links to this article rather than hosting it.
