Bouquet of Roses

Printing and processing instructions:

Assembly - Push the star shaped leaves on the stem, there should be a little of the stem poking from it. After that hot glue the rose on top, there should be enough space in the rose at the bottom for glue to expand and stem to hide.

Rose - should print as it is.

Stem (leaves on bed) - should print as it is, position the leaves with heat afterwards !

Base (flat on bed) - should print as it is, position the leaves with heat afterwards !

Stem (leaves mid air) - this is a tricky one, in an older post here by erin.wang, many had issues printing it. My remix addresses some of these by making the leaf stems thicker and painting custom supports, also, the stem is now longer and looks better in a vase. Print profile has fuzzy modifiers on leaves i personally like them that way.
Print instructions:
- use high-quality filament, which will prevent 90% of problems
- if you encounter any issues, manually set the print speed to 50% (this gives layers more time to cool down)
Post process instructions:
1. very carefully remove supports, start by small pieces from leaves and work your way down to the stem
2. carefully trim any excess material 
3. use heat to remove stringing (i used a cheap filament your results may be better) and carefully heat the branches under leafs
4. pose leaves to a more natural position while the branches are heated

Base (leaves in air) - should print as it is, can fail on removing supports, be careful.


Now, let me address the licensing and give proper credit to the original creators:

Rose (original) - The original model was made by marsmathofficial on Thingiverse and published under CC BY-NC-ND 4.0 DEED, which means the model can be shared and distributed in its original form. DO NOT SHARE REMIXED VERSIONS OF THIS MODEL (nondestructive boolean modifiers in slicer are OK)
I am also sharing the original model; therefore, I am still respecting the CC BY-NC-ND license the original creator chose.

Stem (remixed) - The original model was made by Richard Tracy on Thingiverse and published under CC BY 4.0 DEED which means the model can be shared and distributed in its original form or remixed.

Base (original) - The original model was made by Richard Tracy on Thingiverse and published under CC BY 4.0 DEED which means the model can be shared and distributed in its original form or remixed.

Vase - That's mine, made through MakeMyVase on MakerLab, nothing extra about it.

Update 
I have accepted all valid criticisms of the stem model. Even though I tried to make the branches thicker and tested many types of supports, it was not enough.
Therefore, I made a new remixed model with my own self-modeled leaves. These are printed on the bed (unlike the old ones in the air) and positioned afterwards using heat.
Lately the base model of leaves under the rose was also updated to be printed flat. This will hopefully help to avoid the same problems with the old model. 

I would like to thank you all for printing, sharing your pictures, and commenting.
