I'm think more about making than buying.

Cool, look forward to seeing what you come up with and if it works well

one of those "might buy one day because it seems like a good idea"

the "straws" or tubes would need to be a semi decent size to actually be able to pick up the dirt and grit.

Something like this maybe? Too small? 1.5mm ID PVC Tube Clear Plastic Pipe - High Grade Hose - 1/16" inch - Small Bore | eBay

Could be a good size but long term the PVC would eventually harden - probably need something more flexible like silicone tubing of some kid.

I now realize its going to be of limited use for WW as some of the chips would be too big and would clog the pipes.

That is quite small tubing Elan,
I used tubing like this on the model buildings we were making for wind tunnel testing.
Its quite flexible and glued thru the 2 mm ply walls well with loctite 401 or 416 cyanoacrylide glue.
Fun getting hundreds of lengths of tube this size up a 4 or 500 mm long by 60 or 70 mm square ply tube and out the walls from top to bottom with enough length to route out from under the turntable and hook up on the computer.
This will glue into an end disc no probs with superglue using a conical wedge to hold it until the glue grabs.
Trims flush with a sharp chisel.
I spent 5 years making hundreds of these models and never photographed one.
Guess that means it never happened.
I will bore you with using the micromanipulator to weld the other probes another time when the breeze isn’t blowing the wire away.
More stuff I once did that I know I couldn’t now do.
