Motorcycle Keychain with Spinning Wheels: A Fun Print Project The motorcycle keychain features a pair of spinning wheels that are attached to the body, creating a dynamic design. To assemble the keychain, print the body and wheels separately before attaching them together. Each wheel can be printed as a single part or divided into two components - the rim and tire. The rim fits snugly into the tire, requiring some force to insert it. You can use a hammer or step on the wheel to secure it in place. To fine-tune the fit, print the wheel slightly smaller or larger (about 1-2%). Printing the wheels separately allows for more color options. The rubber part can be printed in black, while the rim can be any color you prefer. You can even add a third color to the body for extra visual interest. When attaching the wheels to the body, ensure they spin freely without any obstructions. If necessary, use a cutter or sandpaper to smooth out imperfections on the parts. The pin that secures the wheels has a press fit, preventing it from coming loose once inserted. To adjust the size, print it slightly smaller or larger (about 1-2%). For those who prefer a simpler design, an alternative body is available in the "body_simple.stl" file. The standard "body.stl" file features more details and a sportier look. To complete the keychain, insert the key ring into the rear end of the body. The parts were printed on an Ender-3 using PLA filament with relatively low speeds (40mm/s) and 0.15mm layer height.
