Need help creating a custom outline box at the highlighted Block[1.8]

In my blocks i have a fild like the blockBounds holding minX,minY&minZ aswell as maxX, maxY, maxZ. No if the player is holding the item of that block i wanna draw a box showing the player how big the block will be and where he can set it. I tried this in DrawBlockHighlight event, but the box is at the players position and not at the position of the highlighted block. How can i fix this?

So this i swhat i currently do:

	@SubscribeEvent
	public void onBlockHighlight(DrawBlockHighlightEvent e){
		if(e.player.getCurrentEquippedItem()!=null){
			Item i = e.player.getCurrentEquippedItem().getItem();
			if(Block.getBlockFromItem(i) instanceof RLMBlockContainer){
				RLMBlockContainer b = (RLMBlockContainer) Block.getBlockFromItem(i);
				BlockPos p = e.target.getBlockPos();
				e.context.drawOutlinedBoundingBox(new AxisAlignedBB(b.dimensions[0], b.dimensions[1],b.dimensions[2],b.dimensions[3], b.dimensions[4], b.dimensions[5]), 100);
			}
		}
	}

And this is how it looks:
