Open it in the customizer. Bracelet stretches a bit, give inner radius so as to sit nicely on your wrist. Set outer radius, set height, and set the text you want on the bracelet, eg a telephone number where you can be reached so you can sleep on the beach while the children play!
Caution: replicatorg 40 is not able to slice single wall bracelet with holes, so by default the bracelet is double the nozzle thick. As a consequence, it is much more rigid than the default stretchlet. If you think you can slice single thickness, change the nozzle diameter to half your nozzle.
When selecting right, the bracelet without text is given, for left the text. Merge these on your software for the dual printing.
I print the bracelet with 0% infill, while the text is printed with 1 layer and 100% infill. The picture is a bracelet with layer height 0.25 mm.
Update: Now working with parts, so customizer will create 3 STL at the same time. Merge part bracelet and text to do dualstrusion
