This is a gragger designed using Autodesk Inventor with every component crafted from high-quality PLA plastic. At the core of its operation lies a clever mechanism, where primary structural elements (top piece, bottom piece, stiff board holder pieces, the gear, and stiff board) revolve around a central dowel rod. A vital feature of this design is the way the gear boasts key slots, allowing the dowel to fit seamlessly into place. Assembled, one of the top piece parts rests above the gear while another is positioned below it. Stiff board holders are nestled in between these structural pieces and the stiff board itself slips in, establishing minimal contact with the gear's rotation. Finally, the handle will glide into any remaining dowel protruding from the main structural elements for secure attachment. To resolve any discrepancies, consult the accompanying assembly image for clarification. The primary components of this gragger, namely "top piece" and "bottom piece," as well as the "stiff board holders," necessitate double printing for proper functionality.
