I loved the look of the low profile feet by benawhite, but wanted it for my Tevo Tornado. I also wanted to just attach it with the one foot screw vs replacing the aluminium bracket that it comes with. So far it is working great.
I ended up replacing the 5m X 12mm screw that attaches the original feet with a 5m X 8mm, but I adjusted the design to be a bit thicker if you want to just use the same screw.
I used 3 shells @ 0.2mm layer height and a raft but depending on how well it sticks to your build plate, you could probably get away with it. No supports needed.
