Skateboard with 4 independently rotate wheels

thingiverse

I design a simple skateboard that consists of four rotating wheels, each moving independently without being restrained by rigid attachments. I engineer the skateboard as a single-print object with movable parts that simplify printing and assembly. To facilitate printer-friendly operation, I carefully design asymmetric rotary joints that can move freely within printed cavities. To print successfully, place the skateboard's left side down. You'll find reference screenshots of this step in Kisslicer to help guide you through the process. No external supports are required for the model; it will maintain stability throughout printing without the need for additional structural components.
