Have fun with your printer!! :D
I just a little while ago gave them some plant first aid. I've never done it before, so it was a total instinctual guess as to what might help. I made a paste of slippery elm bark and put it on all the bends I could find. Hopefully it will act like a cast and give support, but also still be conductive to nutrients (since it is literally, bark, powdered). I figure slippery elm is used in poultices for humans ...it might work!
