I don't think that this one is evil. Just imagine having a few of these illuminating your garden. Or an alley made of 7 meter versions of it. However, you may want to put some kind of reinforced concrete rhizome barrier into the ground as these plants are strong as
dinosaurs and spread like wildfire. New sprouts could probably flip a tank or break a house over night. :-)

One last thing: This one is an really easy print. It prints just fine without support. (See images for details.)

If you print this one, feel free to post a make - I'd really like to see how it works out for you.
