This little container has a screwcap and a hole for a string or a keyring.

The space inside the pendant is a round chamber measuring 10mm of height, with a diameter of 15mm. It's enough for a couple of pills, or maybe a tiny note with some information, a miniature photo or something else you wish to carry with you.

I suggest to print this container with a high resolution, the prints you see in the photo has a 0.2mm layer height but the screw needed that I closed and opened it several times to become smooth. I suggest you to use a concentric infill for the external part, for a better aesthetic.

My printing time for both parts was 1h 15min (with my old Tevo Tornado 3D printer).
