UPDATED 18 Jan 2019 - 4th size (maxi) added - large enough to fit my glasses! (see pics)*
Screwtop containers in four sizes, ideal for beads and other small items. The lids are perfect for holding the beads you're working with while you work.
Of course, can also be used for anything else - lids fit easily but tightly.
100% infill is great for strength and uses little extra filament. Use at least 50% for strength and integrity of thread.
If you're using transparent or shiny lids, use the 'concentric' infill pattern for a much better look (and it prints much faster too.)
