Making the clothes dryer vent filter snout from TPU did not work nearly as well as I expected:

Making it from much stiffer white PETG required moving the front mounting tabs to the middle to allow enough bendiness to snap them into the vent:
Although both pieces barely fit on the MK4’s platform, I made the upper ring first to verify the fit:
If I ever make another, it’ll print as a single top-side-down unit, because the dimensions are now spot on.
From outside, it looks just like the TPU version:
The snood is a cheesecloth tube with shock cord holding it to the snout.
