This bracelet uses 2 prints combined. The first print is of the core, made using a flex filament, which then slots into the second print made using a stronger material.
Okay, so, first off print the soft band.
Second, switch filaments and start the hard beads.
Third, pause the beads print at right around 5mm (will vary depending on your layer height) and place the soft band into the bead print.
Fourth, resume the print.
