This is a print in place model of a two color switch via filament change. This is inspired by check it!
Unlike Check It… it doesn't have slot for magnets since I decided to stop working on this, because I'm not sure how well it works at a distance. But you can try it out and see if it works better for you. Feel free to improve upon it and let me know how it goes!
