Not sure how many people are looking for vacuum mufflers on Thingiverse, but if you are, you've come to the right place!
I somehow managed to lose mine so I designed and printed a new one. To my surprise, it works pretty well! The airflow is not noticeably restricted yet the noise dropped from 90 dBa to 79 dBa. See it in action here: https://www.youtube.com/watch?v=wev-VcMSJIU
Note: I had the inlet open in the garage for testing so the real world sound levels are lower when you're vacuuming in the house.
This fits over a 2" pipe exiting the vacuum canister. I've included the Fusion 360 files if you would like to modify for your own vacuum. I used S3D for the slicing and included the supports for the bottom part. You shouldn't need supports to print the internal structures as I have tried to limit the overhangs to 45*.
Please excuse the rough nature of the print in the photo. It survived 2 power failures and running out of filament once. But it's a vacuum part so I wasn't overly concerned about cosmetic appearance.

Quick and dirty - it's a vacuum!
Notes:
Printed fast with a 0.8 mm nozzle and 0.4 mm layer height. It would take an eternity with a 0.4 mm nozzle.
