Fume extractor with external switch

pictures are coming when I get the possibility to take them
Edit: turns out, the modified lid don't fit into the case with a mounted cable gland. So I have to redesign this part completely. And maybe I need to cut away something from the left half of the case, we will see

the most credit goes to the author of the original thing.
what changes I made:
cartridge: nothing changed, just the unmodified files from the original thing
case: the holes for mounting the lid are smaller because I don't have heat inserts and want to use self tapering screws instead. Also the hole for the female barrel jack connector has a bigger diameter (11mm) because this is needed for the connector I ordered.
lid: I closed the holes for the switch and the LED (although the last didn't work in the exported stl)
Also I placed a 12mm hole for a M12 cable gland instead because I wanted a switch I could place free on the desk like the professionals fume extractors I use at work.

So I added a little case for a switch that's connected to the extractor via a three-core cable.
My switch had a ca. 13x19mm standard case and a built-in 24V-LED. The LED is not very bright at 12V but it works for me. If you want it brighter or only have switches with LEDs for 110V or 230V you can used the original LED hole in the lid.
Then a two-core cable is enough.
I included the Openscad-file for the switch case, for the case you want to change tolerances, the hole for the switch or the cable or if you want to export the two parts of the switch case seperately

fan:
originally a 80x80x38mm fan but I only had an 80x80x25mm fan, so I used 4 M4x10mm spacer bolts and put the fan grill between the spacer bolts and the fan
