Happy Worm Happy worm in 2 version. One joined version and one that prints with a separate head. the separate head version come in 2 sizes, larger and small. The small has slightly different tolerances for the head. However whether large or small be careful putting the head in place as to not break. Matte and silk are significantly weaker than normal PLA Ignoring my own advice ive used Matte gradients from Ziro. along with basic pla from Bambu for the eyes and antennas. 0.2 Layer Height, 10% infill
