Closed Rose Improved

This is a slightly improved version of my closed rose which should slice OK with fairly standard settings , though I would still recommend you set your extrusion width after the first layer at less the 0.4.
I have also added a stem, some petals, thorn and leaf. Just drill a 2mm hole wherever you want the leaves and thorn to go on the stem or whatever else you wish to mount the parts on.
I suggest some gentle heat from a heat gun to mold the leaves and petals to a more organic shape.
