Upgrade to this cool plant hangar I used. I added some more designs to make it stronger plus made it able to rotate and added wall plate and bolt. Since this will hold weight I highly recommend printing this at 100% infill using lines but can be as low as 25% infill. You can print it at standard 0.2mm but for details to come out nice super 0.12mm & 0.08mm works out well. No supports needed, I made the 3MF file print ready I suggest using a brim for the bolt or use a metal rod if you have one.
