Small Plain Grommet

A small 12mm-diameter plain chamfered grommet with a 4mm long/7.5mm wide center post. The eyelet-hole is 4mm in diameter. These are meant to be used with a dab of glue during assembly.

Depending on your printer calibration and settings, you may be able to get them to lightly snap-fit instead, but I've been using them with glue - I didn't want to make them too difficult to snap together because I have joint problems.

I've been using them for mainly decorative purposes on some fake-leather armor. Because they're so small, I wouldn't trust them with anything heavy-use.
