This is a holder I designed to hold 6 of the regular can lid bug covers found here:
https://www.printables.com/model/928800-beer-can-lidsoda-can-lidbug-cover-no-supports-need
No supports needed to build and can print with little infill as this doesn't have much need for strength (unless you've got some rough campers! The sides can be a bit flimsy with just PLA but even if they pop loose from the bottom, they still hold the lids in place and it's a little easier to use.
My rudimentary setup (with my default settings):
