The 3D you're likely referring to is only for blocks and items (and MAYBE entities, maybe, not sure if they've been moved over yet), not for skins. Skins still use hardcoded models so you cannot change the player model (and thus add this skin) without having a mod do it.
Skins do have some sort of "3D" by way of layered textures, ie you can place glasses over your player's eyes, and hair can be over the head, but that's really only providing another voxel to draw the texture you provide in the skin on, and isn't you as the account owner changing the model.

In Minecraft, it is helpful to think of the skin as made up of pixels. A pixel is one square of color on a screen. Minecraft skins come in two sizes - 64 x 64 pixels (a total of 4,096) and 128 x 128 pixels (a whopping total of 16, 384!). When you create a Minecraft skin, there are lots of pixels to fill in, but the various paint tools will help you do this rather quickly.
It's important to consider which surfaces of the skin are visible. For example, the top of the rectangular prism that is the legs is never visible. But the bottom of the head is visible from certain angles because it sticks out from the neck.
Start by heading to the Skin editor website. (Here are some of the best Minecraft skin makers to pick from. For this tutorial, we'd recommend using MinecraftSkins. To start with, the Steve character (male-identifying) shows up as the default skin.
Click and move your mouse to rotate the skin. With your mouse wheel you can zoom in and out on your skin. The color palettes is set using the colors below, and there are tools to draw, fill, and erase. The paint brush tool will fill 1 pixel at a time. Click and drag to continuously paint lines of pixels. The paint bucket tool fills an entire surface of the section of the skin you are on (such as the left arm). Remember, you can always click the undo button to go back a step!
Now you can pick a character to start building from - try to find one that is the closest to the skin you plan to create. You can also chose Alex (female-identifying) from the Model drop down under your skin. And you can pick any skin listed under New Skins or Top Skins to edit.
Next, locate where the mouth and nose of your character will go. Many skins will have no mouth at all, while others will have 4-6 pixels in a row for the mouth. Remember that you can always look up images as a reference.
Make the hair for your character next. When choosing hair color, it is best to choose 2-3 shades of the same color to keep the hair from looking completely flat. Adding some hair over the eyes can give you a swooped bangs look. Longer hair can be tricky because some of the hair will cover the top of the torso.
Start coloring the torso. Decide what kind of neck line you want on the shirt - most shirts do not go straight across the neck and shoulders. Use a darker shade of the shirt color to outline each surface of the torso, and a lighter shade to fill in the shirt. Adding shading - even a little bit - will give your skin depth and make it look more realistic. Plaid shirts, patterned shirts, and striped shirts will take more patience but look really great when finished! Or try making a sports jersey, a hoodie, a jacket, or overalls on the torso of your character.
After the torso is complete, work on the arms and legs of your character. Again, use a darker shade of the clothing color to outline, and a lighter shade of the same color to fill in the clothing. For the legs, try pants, ripped jeans, shorts, a skirt, dress, or kilt for your character. If your character wears shoes, reserve the bottom 3-4 pixels of the legs for sneakers, and more if you want boots or another higher type of shoe.

In Minecraft programming courses, we develop mods, add-ons and more. This list also includes skins for heroes and mods. In the course, the teacher will help not only to create the appearance of the hero but also to properly implement it in the game.
On these squares of body parts of the model, additional elements can be applied on a second transparent background.
You can draw a skin in any editor convenient for you, or use a special program for creating skins: Minecraft Skin Editor, MCSkin3D.
You can download and install the skin through your profile on the official website or through the launcher. Remember, in order for your skin to load correctly, the dimensions must be 64 by 64. However, you can use a 64 by 32 skin.
In another way, you can easily change the skin by replacing the standard one. We need to overwrite the file with the standard skin on ours. However, when changing the base appearance of a character, remember that these changes are only visible to you. After making changes, only you will be able to see the new skin, and absolutely all players from the base will see you as just Steve.
If you are playing the portable version, then you can simply select your file from the tablet gallery (for example) and install it into the skin pack.
Hooray! Now you have learned how to change the skin in Minecraft.
