Anemometer with moving bicycle

thingiverse

Enjoy this anemometer, featured with a sleek bicycle design that's as fascinating to watch in motion. Each part has been carefully crafted by me, allowing it to rotate effortlessly even with gentle winds - I know it might seem useless, but it's definitely a fun novelty to observe. To ensure durability, the central shaft is made from high-quality carbon fiber, eliminating any potential issues that might arise from using PLA material. In order for the anemometer to move freely around its axis, a ball bearing is necessary - and another one is also required for the central blade. I used Autodesk Fusion 360 to design the gears, while all other components were created with Blender. To see the anemometer in action, simply click on this link: https://youtu.be/IMhXD53sVK4. Before you begin assembling the anemometer, it's a good idea to polish all holes and gears - the quality of your 3D printing will determine how smooth the operation is. To start building the anemometer, begin by putting together 01-Blade_base and 02-Blade (three pieces). Place a ball bearing in the rear hole and attach the 03-Blade_base gear using glue, just as shown in the provided image. A shaft with a diameter of 4mm and a length of 16cm will be needed; you can use any material you prefer - I opted for carbon fiber. As an added lock to prevent the blade from moving too freely, I used a clothespin typically found on RC cars. Next, insert 09-support into the shaft followed by 10-upper_pivot in its center. With that complete, you can now put in 12-rudder - apply some glue to ensure it doesn't shift out of place. You'll also need a ball bearing under 10-upper_pivot and another beneath that which should be positioned inside 11-bottom_pivot, a separate rod measuring at least 16cm tall. With those steps complete, you can proceed to assemble the bicycle separately. Begin by inserting 04-Chassis_bicyclette, making sure all holes are polished smooth, and attach 08-Front_gear in the front hole - on the opposite side, insert 05-Wheel, securing it with a toothpick. Performing the same operation at the rear using 06-rear_gear and 05-wheel will result in a smooth operation of your bicycle. Once complete, place 07-Central_gear into the central hole followed by 13-Pedal. Now that your bicycle is built, double-check to ensure all gears are operating freely without any obstacles or excessive force. Place the completed bicycle into 09-support, positioning it according to the provided image (make sure the joint is at the center of the bike). Apply a slight angle of counterclockwise inclination from above. Assemble the blade so that 08-Front_gear aligns closely with 03-Blade_base gear - and ensure smooth operation by watching for any sign of interference. Once you're satisfied that everything's in order, apply glue to 09-support. With that final step completed, enjoy the simple yet mesmerizing movement of your bicycle anemometer as it dances with the wind, albeit aimlessly.
