Kruve Coffee Sifter Extender

A Kruve Sifter is required!This extender stacks on itself, allowing as many filters as desired in the sift.The main idea is to profile a grinder, much like a more expensive Particle Size Analyzer does and less for brewing purposes. The extenders stack on the lower filter holder of the Kruve set, the top filter holder is not used. The extender has it's own lid. I was able to stack 7 filters and still able to get a good profile from 18 grams of grinds, I'm not sure I'd go more than 25 grams as the extender depth is purposely shallow for high stacking. I also used a dental vibrating machine to speed up the process, it worked well but hand shaking was still necessary. Sep-25 Update: Fixed lid, added Fusion360 file
