Duplo Bicycle (Tricycle)

thingiverse

I design a Duplo tricycle for my daughter Lisa. I instruct the printer to create four sturdy wheels and four secure pins. To add extra strength, I set the infill to its highest level. I prepare two versions of the body: one uses the pins as connecting rods, while the other employs a threaded rod, washers, and nuts for assembly, providing a smoother ride than the pin-based version.
