Fume Extractor Light Slider

My fume extractor is very very old and it's falling apart. I tried to search for the piece, but it costs close to 12€ + shipping. I thought I might be able to buy the whole module since it's a very basic piece but it costs over the price of a new fume extractor, so I decided to design my own slider.

This is what I came up with. I printed it with the slider pointing upwards.

I thinkt it will work with ...Whirlpool Indesit 481231038865 C00312524 and I think it is the same as an IKEA one and also Aspes. ELICA FAGOR 3034AHA
