a vacuum (buchner) flask and funnel assembly
warning: this entire thing is only going to be as chemically resistant as the filament you make it out of - do your own research and use this thing at your own risk.
i couldn't find something quite like this thing online so I made it myself for myself and for you to use, if you just happen to be reading this!
it's definitely not a perfect replacement for real glassware, however if you're broke it could serve you for a while
it is supposed to be almost exclusively printed and does not need glue to be assembled, however I highly encourage using teflon plumbing tape on the screw thread to make it airtight (and if you're gonna be using this for chemistry purposes you prolly already have it, else go get yourself some, it's very useful).
anyway, as for printing;
I recommend printing all of the files in the orientation they're already placed and adding tree supports for the flask's vacuum port(the vac nipple is designed by @Jose_30572 btw; the only thing i didn't make from scratch) and maybe the flask's lip. the funnel and discs should require no supports and no brim to print, but judge by your own machine.
also on disc sizes - smaller tolerances = better, as you want less air moving through those gaps. you could technically use some glue or smth but just keep in mind it's chemical resistance to the solvents and stuff that you're going to be using with this

p.s. i may or may not add more sizes in the future
