Hi All,

In this instructable, I will share how to paint 3d printed baby groot planter, using acrylic paints and will use 3d printed layer line to our advantage.

Hope you like it

Step 1: What Do We Need ?

3d printed baby groot planter
Acrylic paints
0.5 inch thick brush
Very thin brush
White sheet of paper
White ink marker
Varnish spray for acrylic

Step 2: 3d Print

You can search and download a suitable model from Thingiverse
I used "baby groot pot (re-remix) by aricard" link https://www.thingiverse.com/thing:3357065
My printer settings were as below
- Slicer: Cura 4.8
- Resolution: 0.28
- Infill: 10%
- Supports : Tree, everywhere, angle 60°
- Filament: black PLA
- Printing time: 14 hrs
- Scale : 150% ( height 15cm)

Step 3: Base Color

If the 3d printed Groot is not black, then we must first paint it with a thin black acrylic paint
Let it dry for a day before we continue
Take the dark brown acrylic color and spread it on a white sheet of paper as shown
Using a plain white sheet helps us to understand what colors will look like when mixed
Using a thick (0.5") brush, apply a very thin coat of paint on 3d printed Groot
Before the dark brown paint dries, dry brush with some yellow
Again use paper to thin out the paint
Since the brown paint is wet, the yellow paint mixed with it and give a light brown wooden look
This will highlight the raised areas as a light shade of brown
Before we continue, we will leave this to dry for 2 to 3 hours
I covered the eyes too, donot worry, we will fix it later
I didn't use any primer so that I could use 3dprinter's layer as wood texture
Don't use an excessive amount of paint, as this will fill all the texture etc

Step 4: Green Veins

Using some green acrylic paints highlight some veins on the hands
On it's head paint green in the cracks to green moss growth look

Step 5: Eyes

It is easy to scrape off the acrylic paint from the eyes
I used a toothpick to remove any paint
As per some images on the internet, the iris is black and the sclera is red (the white part of our eye is called sclera)
Painted sclera as a mixture of red-brown color and left the eye as black
If you are not able to scrape the paint, use black acrylic paint on it
To fake light reflection on the eye, use a white marker to draw the reflection
