Very nice mate, now all you gotta do is 3d print the level with bubble and you're set 
It wasn't a mod / part to earn dollars from but purely as mine was cracked and I could make it for free instead of paying $20 it get it from overseas but it took a bit of designing and testing - painful little thing to get the bubble sitting the same as the original.
Ebay has the same size spirit bubbles for $4 shipped to your door for 20 of them = 20 cents each. The down side is that the lines are different but I still had the spirit bubble so wasn't my concern. It's just available for anyone that is in my situation.
Enjoy
