Is there any filament that is unaffected by methanol?
I'm looking to print a bottle holder with swing-in funnel to aid filling it with methanol. At the moment, we use a single funnel that has a habit of being taken for other uses and not returned, so having a static funnel would be better.
The filament being used would have to resist becoming structurally weakened by exposure to methanol, and also not leach materials into the methanol which is drawn up from the bottle to clean very intricate machinery.
I realise this might be difficult as filaments will have different additives between colours and manufacturers that are often not specified. Any materials scientists out there have any recommendations? I have at hand a moderate amount of PLA, ABS and PETG.

For chemical inertness I would look at nylon.
It is high temperature, so you might want to design your funnel and pay someone to print it for you.
