I'm working on a 3D printed windmill and wind tunnel, which are the outcomes of my testing that took place from June 2014 to October 2015. I updated the files in 2015 to include a better printable model and a shell version showcasing possible wing ranges. Print Settings Rafts: Yes Supports: Yes Resolution: Less than 0.2 mm Infill: Yes Notes: The Mill is challenging to print in ABS or PLA! Support must be set at 45 degrees for optimal results. If your printer suffers from warping, ensure the perf board is securely mounted with extra clips. Post-Printing A small version measures 7 cm in diameter. How I Designed This The concept of a windmill came about long ago due to my experiences with kites (speed-wing type) and other hobbies like windsurfing. Additional inspiration was drawn from Mc Escher's Spheres and my fascination with bio-metric 3D design and the 3D printing revolution. To incorporate it more seamlessly into nature, I utilized the mathematical spiral formula and varied wing shapes. The initial results show a 30 cm diameter type capable of generating electricity at wind speeds exceeding 3 bf (enough to charge a smartphone battery). To make it functional, I employed two nails without their heads or other strong metal components that fit snugly in the holes. The mill itself must be able to rotate freely. (Apply a small amount of oil) I will soon upload a version with an E motor mount.
