Lighthouse lens

I'm working on Shipyards lighthouse Utö. The scale is quite large: 1:72, and it give me the possibility to reproduce the original lens. It's maddening! 😁 Anyone who have tried such work, and probably find a simpler way to this kind of work? The lense's valves are made with printed overhead film ( I used msPaint), cut and glued with UHU plastic.The frame is made with 0.5 mm painted paper. Tips and tricks are welcome.
