Giant wheel / ferris wheel / grande roue / 1 meter

20 04 18 New files for the wheel spoke inner section are available for printing on smaller machines like Ender 3. The spokes have been divided into three sections. A small junction part is added to ensure alignment and solidity. Everything must be glued and aligned. Three files are included in a single ZIP file: Grande roue wheel spoke inner section 2 parts inner.zip This project began when I saw this type of Wheel in Hardelot a few months ago. It made sense to create a large project with a small 3D machine to demonstrate its feasibility. After researching internet for drawings and pictures of real things, my choice was made for the RR35 from mondial Rides in Netherland. This company designed the Paris Wheel owned by Marcel Campion. The RR35 is the smaller model but has the type of pod I wanted. It stands 35 meters high, so I decided to scale mine at 1/35. My project was created on SOLIDWORKS for design and printed on my CR10 stock machine. The wheel is quite large, standing 1 meter tall and almost as wide. For those who frequently adjust bed leveling, be aware that I leveled the bed before starting the project and never adjusted it again after printing hundreds of parts. Tuning was done using a paper sheet, and that's all. A Leroy Merlin Mirror is on the bed. For those who often complain about part adhesion on the bed, be aware that I use Scotch glue stick on the bed: once before starting and a second time on top of the first one after printing the wheel and legs before fitting the pods and ground structure. That's all. This machine does not require many adjustments from my perspective. All prints were made with PLA at 0.2 mm layer thickness, speed 45 mm/s, bed temperature 60 °C, and filament temperature around 225 °C. Pods required support. Infill should be 20% most of the time, increasing it for the legs. Mine seems a bit too flexible with 20%, but it works. Most of the assembly is made using M2 x 12 mm screws with 45° heads. A large quantity is needed, but it's not expensive. French supplier: https://www.bricovis.fr/std/accueil.php You'll also need some M2x20, nuts M2, and a few M3 screws for the legs if you prefer to use them. You can design 3mm rods to fit inside the assembly. This project includes holes for screws that are slightly too small because I prefer to drill at exact dimensions. You will need 2 & 2.5 & 3 & 4 mm drills. There are some ball bearings, including those for pods vertical rotation, pods rotation during wheel rotation, and wheel rotation. On the pods, you'll need 48: 604ZZ 4x12x4. On the wheel junction connectors, you'll need 48 MR63ZZ 3x6x2.5. For the wheel main rotation, you'll need two 604ZZ 4x12x4. These can be easily found on Ebay. You will also need some 4mm rods and 3mm rods. This project is complete on the construction point of view but not finished on the electronic side. It can run with 5V power from a small cell phone power pack or plugged into a cell phone USB charger. The USB power pack is located in the ground structure. Rotation is made using a small geared motor already used in the wind turbine project, with a different gear ratio to provide 2 RPM, which is the maximum speed on the RR35 data sheet. You can find it on Ebay: N20 Micro Gear Motor 6 V -100 tr/min In the files, parts are stored in Zip files per function, making it easy to identify which parts go where. Looking at the pictures will also help. For final assembly, use a plate to have good positioning of the leg. I suggest printing the ground structure before fitting the ground connectors definitively. It required moving some leg ground plates to adjust with the ground structure. I would like to add some people scaled at 1/35 but haven't found them yet. Playmobil people should fit, then if you have children playing with playmobil and enough space... I will add some files when Arduino nano is ready to control some lighting and rotation speed. I want a ramp up and down and stop always in the same position like the real thing. Hope you'll enjoy this project.
