I didn't want the collection part at the bottom, just for bread crumbs (or other ground stuff like dried cooking herbs or soft nuts) to drop to the counter or into a bowl. Also, it needed to be bigger for this to work.
Kudos to @MichalFanta for a great design that I just coned off the threads of the middle bit and then increased the size of that and the lid to the size I wanted. Not the smallest glitch! The parts fit great together, printed perfectly and the grinder works really well!
