My camera broke as well...
I pulled out the silver ring that surrounded the original broken glass (it is easy to remove using a small pliers), cleaned all the broken glass pieces and ordered a flat glass watch crystal diameter 29mm Thick 1mm on aliexpress
Once it arrives i believe I can glue all the parts together again, almost like the original camera.
(search for "flat glass watch crystal diameter 29mm thick 1mm" on aliexpress, costs less than 2 dollars)
