Deformable Roses for thorny stem with nice leaves

In the print settings tab select “Spiral Vase mode”. 

A little over-extrusion width (e.g. 0.6 mm for 0.4 nozzle) does not hurt, then it is more stable.

The files were provided by Lucretia @bergfex55_505553 in order to be able to present the post-processing. Thank you very much! 

For post-processing, you'll need a heat gun or hair dryer and a Tool to devide the layers by heating up. 
 

(1) Print the Roses in Spiral Vase Mode - I print with PETG or PLA. PETG is .
PETG is easier at the beginning to get used to hot air dosing. You have to be a little more careful with PLA, as it is less heat resistant, but it works just fine! If it's your first time using hot air or you're a gross motor expert (I actually am, too), I recommend starting with PETG.  

(2) Use your heat gun carefully from the side only in the upper part of the flower. At the same time, use a tool to prevent the warming layers from sticking to each other. Don't be too shy, you can bend the leaves down nicely.

Be a little bit careful with PLA, it is less heat resistant and deforms very quickly. I prefer PETG, but with a little caution you can also use PLA!
 

My personal experience with PLA so far is: It works great, but deforms very quickly, so use the tool wisely to prevent sticking. The PLA also cools down more slowly: it allows you a little more time to bring it into a nice shape after heating, or when viewed from the other side, you pause a little longer between each rotation so that it stays in the shape you want!
Learn from my mistakes: Don't grab PLA roses between your fingers too quickly: The PLA may not be completely solidified and you will then press in the lower walls. You don't want that :) PLA is available in so many great colors that if you follow the tips, your roses will also be simply wonderful!

My Heat gun has a maximum Heating of 350°C and High Wind Volume of 300L/Min. With a Hair dryer it may take a little longer. The more precisely you can direct the air jet, the better you can shape your rose. Use any attachments you may have. 

To distinguish the shafts, I use a clay modeling tool. But you can also just use a screwdriver or a small pair of pliers. Of course, it should not melt when heated. 

(3) Use your tool to gently pull the heated surface into your desired shape.

Allow the material to cool down for a short time afterwards to consolidate the new shape. 

Twist the rose and work it on all sides until you're satisfied. 

(4) To adjust the inner petals as well, you can use the heat gun to gently aim into the flower from above and adjust these leaves.

Be careful that the individual layers do not stick together. 

(5) Final Result: 

(6) Combine your rose with Lucretia's deformable leaves and rose stem for a wonderful rose design:
