Remix of the lid to accept a cheap Niche Zero bellows. At time of creation these were £3.50/€4/$5 + delivery on Ali Express. Search for niche zero bellows (link). See the screenshot of measurements from a listing if the link doesn't work.
The diameter of the bottom opening of the bellows is 42mm.
I've created a flat top and a tapered top version. The tapered looks neater, but the flat top moves more air as the bellow compress more.
STL files should already be in the correct orientation. Printed without supports.
