Conventions « Values: Each size is the envelope of the makers' datasheets, one lineage per maker. D and H are the largest maximum the listed makers state (the widest band); the model is built at that maximum.
« Sleeve and can: A printed sleeve D across from the negative end at Z = 0, its lips folded over both ends, a rolled crimp neck below the positive end. Sleeve thickness, lips and crimp are house style.
« Positive end: Flat top: a white insulating ring and a nickel cap with a raised centre and four vents, its top at H. No maker dimensions the cap, the ring or the vents.
« Marking: The written -out CommunityCAD logo printed in white on the sleeve. Chemistry, capacity and the maker's print aren't geometry.
