Your model name is not a valid Java name!

I have been making a mod for version 1.12.2, but I created a model in Blockbench which is a helmet, but when wanting to import it as java I get that error, the model code is the following:

// Made with Blockbench 3.7.5
// Exported for Minecraft version 1.15
// Paste this class into your mod and generate all required imports

public class MEGO extends EntityModel<Entity> {
    private final ModelRenderer bone;

    public MEGO() {
        textureWidth = 16;
        textureHeight = 16;

        bone = new ModelRenderer(this);
        bone.setRotationPoint(0.0F, 24.0F, 0.0F);
        bone.setTextureOffset(0, 10).addBox(-6.0F, -2.0F, -8.0F, 12.0F, 2.0F, 2.0F, 0.0F, false);
