Fixing broken illuminator carrier for Zeiss IM microscope

I ordered a second hand illuminator carrier off ebay – it was cheap but I did not realize it was broken!

However, I think I have successfully fixed it.


Damaged carrier as it arrived from ebay – these photos show that the plastic gear strip is cracked. On the other side of the illuminator it has also had its teeth stripped:
