I had exactly the same problem a few years ago before I had a 3D printer which I would definitely attempt now. I used the good lever to make a mould with plaster of Paris. Then mounted the broken end in the mould with a strengthening rod inserted into a drilled hole in the stub. Resin mixed with a bit of fibre glass for strength was poured into the remaining gap. The cured and finished item was rubbed down and painted and it is difficult to tell the difference.
