These things are awesome. I use them for storage, organization, whatever. the lids have lots of tolerance and only need a little twisting, so you can put them on one-handed, or let kids play with them to teach them complex shapes. They print super easy and will really show off whatever filament you print them in.(I'd love to see this in Polyalchemy Elixer)
I hope you like 'em! Don't forget to post makes down below.
