Not so much made as cobbled together. I'm replacing our 15+ year old heat recovery ventilation system and need to clean out the ducts. It's all 4" and chimney brushes are far too coarse, just needs something to budge spiders and dead skin. Also drain rods are a bit too clumsy for delicate ducts including the flexible bits.
Looking around there wasn't anything easily available that wasn't going to cost 20 quid or more and you knew that it would be a pile of rubbish going straight to land fill.
Then, like most good ideas it came to me while walking the pooch. I have electrical duct rods, and I have polishing mops for the bench grinder. One M5 bolt and two repair washers later and the mark one duct sweeper is ready to go.
You can get various mops from very soft up to stiff close stitched of even scotchbrite so should meet every eventuality.

MIL in Canada had a heat recovery full ventilation system in th bungalow with central vacuum cleaning system that had a couple of wall points in each room for a 15 foot long vacuum cleaner tube.
Every year the cleaning man would come , blank off all vents but one that was the farthest away from the collector or filter tank , remove the collector . Then then using a very hairy sheepskin ball on a long strong light reeled cord would suck the ball along the longest run with his big vacuum cleaner till it entered his cleaner .
Then he switched it off removed the ball and tied on a length of " Gutter Protector. Avoid blockages. Reduce maintenance. (coopersofstortford.co.uk) "
to the cord . pushed the cord and brush in the duct and set the cleaner very tightly to th wall plate using a masking plate & soft tape over the open hole . He'd then nip down the cellar and slowly pulled the three foot of caterpillar back to the collector bin , anything that was loosened got sucked up into his big powerful industrial vacuum .
He also did the vacuum tube central cleaning system for the three bedroomed in a similar manner . The whole bungalow usually took him less than an hour .
