Dragon Boat Mechanical Device

After assembly, dimensions are approximately 160×60×132 mm

The head, tail, drumsticks, oars, water ripples, small fish, and zongzi are all movable

Please rotate clockwise (backward); reversing the rotation will cause the drumstick’s crankshaft to jam

(Of course, you can reverse the installation of the drumstick’s crankshaft, which means rotating counterclockwise. In fact, this way the oars and drumsticks seem to work together better, though the final result may differ slightly from my tests…)

There is a noticeable difference in shrinkage rates between wood PLA and other materials, so tolerances have been set relatively conservatively. If using wood, the fit may be slightly tight, requiring minor sanding or reaming in some areas

Non-printed parts require four M2×6 screws and one M2.5×10 screw; please do not tighten these screws completely

If you encounter any issues during assembly or get stuck somewhere, please leave a message

Assembly instructions are as follows

Green lines indicate alignment points, while red circles mark pre-drilled holes. If the fit is too loose, you can use glue or insert a short piece of filament

The top cover must first be inserted horizontally and then rotated 90 degrees; the tail rod follows a similar procedure
