Summary

I needed a mount for 1/2" wooden dowels to hang my plant lights which was also minimal and small form factor. This, with a single screw does the trick.

Print in whatever material you like. As long as you aren't hanging a lot of weight. I printed mine in PLA.

WARNING: Do not put much weight on these. They're okay for holding small LED lights, but will definitely break if you have much of a load. Source: experience.
