Thanks, appreciate the replies. Especially the above which does make me 
think that just because in the modern world I've grown accustomed to the 
idea of "if I can think of it China must make it and it must be easily 
obtainable on the internet for pennies" doesn't make it necessarily 
true. Rummaging around on Aliexpress and Ebay seems to support this, the 
grommet-type thing I want isn't really a thing at all.

I settled on ordering an assortment of the double sided rubber "bung" 
type closed grommets which I planned to cut the central section out of 
leaving a small rim around the inner edge that I will glue the dust 
filters to directly. When they need cleaning I'll pop the whole grommet 
out and put 'em in the dishwasher. A dodgy hack of course but that's my 
favourite kind of "fix". Enemy of good enough is perfect etc etc.

The inverted filter dustbin idea was cool, I hadn't thought of that.

The goalposts on that specific job ended up inevitably moving again and 
I eventually had to put my foot down. The server is moving to a less 
hostile environment and the workshop will have some fanless sealed units 
for the end users to interact with instead, much less of a headache all 
round.

Cheers
