Vertical Wind Turbine

thingiverse

Now updated with MK3.1 - Which unlocks full power potential!\nThe vertical turbine design spins freely in the wind or can be paired with a motor for maximum energy generation.\nThe motor used in my design is a robust 28mm diameter printer motor; if you choose a smaller motor, you might need to print a spacer for optimal fitment.\nTo get started, print Arms_Gear and Motor Gear files for mechanical advantage or switch to Arms_Pulley and Motor_Pulley files with an elastic band for a pulley system.\nThe arms can be attached to the turbine using 2-4 x M4 bolts, each at least 25mm long.\nBuild the turbine in layers, as I did with my two-layer version, showcased in the image.\nThe design comes with Arms_Top and Arms_Bottom files that combine to form one set; you'll need multiple sets depending on your turbine's tier level.\nThe standard skateboard bearings and 8mm threaded rod are essential components - a minimum length of 200mm is recommended for single-tier turbines.\nSecure the Blades to the arms using M4 machine screws/bolts, then add a nut on the other side; at least 20mm long screws are suggested for single blades or 25-30mm for doubled-up blades.\nFor the latest updates and insights, visit my website - http://samrobmoe-design.co.uk/projects/hobby-projects/vertical-axis-wind-turbine/ (Thanks to 3D_PP for pointing out the broken link!)\nImportant Safety Note:\nThe wind turbine must be securely mounted at your own risk. I am not liable for any damages resulting from the turbine coming loose and/or breaking during use.\nPrint Settings:\nTips: Print the Blades and possibly the bottom mount with supports on!\nPost-Printing Instructions:\nAttach a nylock nut to the end of the threaded rod, then slide it through the bottom of the mount. Secure another nut on the other side to keep the rod firmly in place.\nThe bearings fit snugly into holes on the Top part and should face downwards towards the mount.\nThe blades are attached to the arms using M4 machine screws/bolts on the top part.\nCable tie the turbine down through the holes cut through the side of the bottom mount; I used a balcony railing for stability.\nDesign Philosophy:\nI drew inspiration from various designs, focusing on shapes that emerge in most turbine designs.\nThis is the MK2 version of the turbine, while MK1 had several iterations centered around blade design.
