Garden light cover

Hello,After a couple of years, the garden light cover started to have cracks (sun, rain, snow and temperature). I found another model here, but it doesn't fit. I decided to model it from scratch. Fit well, but happy to modify according to comments. Now printed in spare PLA but good for testing. The lamp was bought a couple of years back by Leroy Merlin or Castorama - for reference.Thanks
