Fellow Coffee Vacuum Canister Stacking Ring

This is a stacking ring for the Fellow Vacuum Canisters. These canisters are great for storing coffee and it's nice to be able to stack them for compact storage on a counter top, without them sliding off. I find I can stack two tall canisters or all three sizes, for compact storage on my counter top. The ring can be printed with 0.2mm layer height, 15% infill and no supports. I have successfully printed these in PETG, but see no reason why they can't be printed in your material of choice.
