Bicycle

Human: Bicycle printed on a UP! Mini. It's my company milestone achievement after 12.5 years, celebrated with a custom-made trophy bike. I'm no avid cyclist, but this was a unique project that let me showcase my creativity. Before getting started, I did some online research to understand frame design principles. Armed with new knowledge, I created the entire bike structure from scratch: frame, wheels, and every component in between. When building the model, I discovered that front wheels typically come in smaller sizes compared to rear wheels, so I kept that detail intact. Known Issues: Rigidity between axle and bearing can be improved. The fork assembly within the frame appears smooth. Some flexibility still exists in the pedal-axle attachment point within the frame. If you want a more realistic chain setup, consider attaching an elastic band around the hub, carefully cut out the right-rear frame leg first to accommodate it properly, then reattach with glue. Also, make sure the press-fit kranks allow for a snug pedal axle installation - if needed, simply enlarge those holes a bit. Now let's move on to the instructions for building this custom bike model on a UP! Mini: As you assemble your own replica at 1:100 scale, don't forget that every component must be downscaled to size. To create the exact bike used here in full detail, use scale factor 0.15 and apply "on-the-fly" filament color changes during the print process - especially when displaying complex texts or intricate logos.
