Windtunnel for MC_Escher_WindMill

pinshape

I am currently working on two ambitious projects: a 3D printed windmill and an innovative wind tunnel. These designs represent the culmination of my testing efforts spanning from June 2014 to October 2015. The wind tunnel is meticulously crafted, drawing inspiration from established versions that have proven their effectiveness. Its unique shape expertly harnesses the Venturi effect, which increases airspeed by creating differences in air pressure. In a bold attempt to enhance airflow, I incorporated internal air-tubes into the design, allowing for additional air to enter and circulate. The spherical windmill is perfectly suited to its round housing, taking full advantage of the available space within the tunnel. When scaling up the MC Escher mill to fit inside the tunnel, be sure to allow a 5% margin due to the mill's tendency to expand when in motion, which could otherwise cause it to collide with the tunnel walls. **Print Settings** * Rafts: Yes * Supports: Yes * Resolution: 0.2mm * Infill: No * Notes: The shell was printed hollow to minimize material usage and optimize print time. When scaling up the MC Escher mill, keep in mind that it will expand by approximately 5% when in motion. To prevent collisions with the tunnel walls, make sure to leave sufficient clearance. The caps have proven to be a weak point, prone to breaking under stress. For now, I recommend using superglue to hold them together and prevent further damage or the need for reprinting.
