Attached is a plant hanger that I use myself. I have included both plasmacam file and also the dxf. I designed the hanger and they are cut from 14 gauge. You can bend the arms to whatever angle you want. You can bend them so you have two plant hangers or you can fold both arms until they meet and make it one heavy duty hanger. I have hung some very heavy planters on these and they work great.
Hope someone finds this useful.
