Hi! When I actually used the Bambu Lab P1S printer, I found that every time I changed the color, a large amount of waste material was discharged and dropped to the ground, which was very annoying. So I read through the works of many experts on the Internet. Although the functions are good, they are not the effect I want. So I measured the size myself, made one myself, tried it, and the effect was pretty good. I share it with everyone here, hoping it can help everyone!
