Hello everyone, with this model I tried to recreate a rose that manages to bloom. As for the stem you will have to glue the screw to the stem then insert the cone nut and finally the leaves at the base of the rose, to complete everything screw the petals in all three layers together it will be much simpler than screwing one layer at a time. Thank you!!

I've noticed several comments that talk about the screw being too tight and people not being able to screw the body of the rose onto the stem well, most likely due to the different filaments used. Personally I used Polyterra Forrest Green filament from Polymaker. A solution could be to only scale the screw to 97%.
