Heinz 73mm Tin Can Stacking Ring

by DB3DUK

PETG suggested for long-term durability but PLA (ideally +/Pro) will probably suffice. With PETG, I found the bridging over the bottom channel was a bit rough and it affected how well it fits on the rim of the tin can. Perhaps scaling up slightly in the Z direction would allow enough space for it not to matter.   PETG supports were very difficult to remove in such a narrow channel and resulted in some chewing up of the walls. Printing PETG with PLA supports on the Prusa XL (Soluble Full profile - no top gap) worked really well. This could presumably also be done on Bambu Lab printers with AMS units, but with considerably more filament waste and time.
