It is apparently a heartshaped CLIP of some type! Maybe we can use it as a bookmark, a paperclip, a hair clip, or just as a decoration.
Customizable. Crafted for someone special.
(NOTICE: The photographs depict an older revision. The most recent revision has bigger eyelets up top.)
SCAD and the STL files default option to a 1mm-thick clip. I have not really printed the 1mm variation, but I printed a 2mm-thick copy on a Matter-O-Matic (see pictures). At 2mm, it was a little too hard for holding multiple sheets of paper. I will attempt next time to a 1mm variant I am at the printer.
Span and depth are tunable in Customizer or in the script.
