Complex but fun! It is based on the simple design of some turbine blades, but with a twist (get it?) -- it can sit on your dek and hold watever you want to put in it! Small plants, pens, goodies, etc. Perfect for the work-from-home life. Oh, and it is optimized for easy printing. I designed the blades at such an angle that they will not need much supports, which makes them great for pritinting using either FDM or Resin printers. The size is adjustable to your liking, so make the most out of it. Enjoy!
