[1.7.10] Increase size of rendered item?

[Bugzoo]

I have a block and an item renders on it. I need the item to get bigger, because it is too small. Here is my code

 

GL11.glPushMatrix();
	RenderItem.renderInFrame = true;
	GL11.glTranslatef((float) ((float)x + .5), (float) ((float)y + 0.1), (float) ((float)z + 0.2));
	GL11.glRotatef((float) 90, 180, 0, 1);
	RenderManager.instance.renderEntityWithPosYaw(entMix, 0.0D, 0.1D, 0.0D, 90.0F, 0.0F);
	RenderItem.renderInFrame = false;
	GL11.glPopMatrix();
