Isn’t it dangerous to put components inside which could ignite the acetone vapor?
Yes it is dangerous to put spark emitting devices into acetone vapor, the LED light is sealed and very little chance of producing a spark and the fan motor is a brush less fan so it also has very little chance of producing a spark, The switch and the LED power supply are in a compartment below and sealed from vapor and the switch is only switching very low currant so there is very little chance of it producing a spark anyway.
I have two different glass domes, they both fit
138mm inside and 142mm outside diameter
134mm inside and 140 outside diameter
What are the dimensions of the glass dome? Specifically the base diameter.
