There is a complete model included that can be printed for single color filament, like silk PLA

then there are the separate files, which allows for the Lily petal to be printed separately in a different color for added aesthetic beauty.

File would need to be sized for specific arm. there are two petal files, one is thinner - this is if you have a 0.2 nozzle, otherwise you need to print the slightly thicker one for it to slice correctly.

Supports required suggest print at 0.1 mm layers or lower for smooth finish.

i printed the bracelet with the opening on the bed, using supports - so they really just fill up the inside of the bracelet - - the top where you will see more prominent layer lines is then hidden by the flower.

The flower and stimmel i printed with a brim pointing directly up, requiring no supports.
