This is a sample of soda can cover emoticons series bundle. based on my own need sometimes I can't finish my drink at a time and need to keep it in a fridge, or sometimes brought it inside a car while travelling so I think a cap or a cover will be a good idea to maintain the taste still good to drink for later day. also to protect them from spilling.
I'm using two materials for this, the outer part was printed with PLA for stronger and clean looks and the inner part with TPU for tighter airlock and liquid.
*for printing with no AMS, basically you can manually print the first layer with emoticons image until it's done, change filament, and then continue printing for second layer without removing the first print from bed plate. just clean the test print part made by your printer at first.
and I've try that printing with multiple objects at once without AMS can be a little tricky, so I guess that will be easier if just print it one by one.
