Bit of a mashup between:
Rose and stem

And

Printable Rose Flower
by Jerrill December 15, 2014

Like others mentioned, in the makes of patwik's model, I had print quality issues due to wall thickness and a noticeable hole near the base of the bud, I assume this is fdm/resin designing, but i'm not sure. However the simple thorny stem was perfect for my taste.

Added the threaded port from patwik's onto Jerrill's Printable Rose Flower, and re-sized it slightly to fit better to the stem.

Stems should be printed upside down (threads down) support needed on Cartesian (sliding bed) printers at a few spots due to thin parts wobbling. Core XY and Delta may not need. I found organic/tree supports worked well for this. Painted a small dot about 40% of the way up, and again around 75%. Also painted the "flange" surface of the stem, below the threads. The surface that meets the bottom the bud. would recommend this for all printers

Bud prints ok with a 0.4mm nozzle, a bit stringy... but beautiful with 0.25 nozzle. stem printed with 0.4mm nozzle print upright, auto painted supports at top of threaded portion "ceiling". I used organic, probably doesn't matter.
