String / Twine Clamp

I needed a way to hang a grow light, and found something here https://makerworld.com/en/models/1270610-string-clamp#profileId-1745978 but wanted some other features, so made my own version from scratch. Easy to grip, and has a post that you can wrap string around to hold while you secure nut hold-down. Can also be used for securing things for camping, etc.
