I designed this to replace the light covers on an old cooker/hob fume extractor. It's a Philips branded extractor but seems to be pretty generic and these should fit Philips, Whirlpool, Elica, Bauknecht, Firenzi and Ignis.
I've reinforced the clips that slot into the extractor light opening to make them quite a bit sturdier than the original part.
It should slot into the lip of the light cover opening(left side) and you can use the existing screw to secure the right side.
Best to print in something clear or translucent to allow the light through. I used clear ABS as it prints with a frosted look the defuses the light the same as the original part.
Dimensions: 171mm x 65.5mm x 6mm(Original part was 170mmx65mm, I oversized slightly as it fits better that way).
STL and STEP files included.
Add a little support material under the clips.
