Sealed Lead Acid Battery Screw Terminal Cover

I use lead acid batteries to power all sorts of things in the field. When at home, I stick them in the corner of the project room. I don't like that the terminals are just sticking out waiting for a metal object to fall on them.

I printed these from ABS, applied some glue, then used a press to force fit the nut. After letting them dry, they cover the post and capture a washer!
