A 15 cm model of an ancient paddle steamer (wheel boat). Need glue!!! Superglue works fine if printed in PLA. No AMS needed. The boat floats on water, and the wheels can rotate. This model is inspired by a ship model one of my elementary teachers gave me, and is a part of my childhood memory, similar to the cargo ship I posted earlier.

Optionally, you can add two thin rubber bands in the hull, as guided in the instructions below. This will allow the wheels to rotate back if you tighten the spring (by rotating the wheels in the opposite direction) before releasing them. Doing so will allow the boat to race around 25 cm (10 in), but the distance is highly dependent on the length, thickness, and tension of the rubber bands and the number of rotations before releasing the wheels.

Instruction on how to assemble this model is given at the end of this description. I have built this model 3 times, and any feedback, such as ratings and comments, would be greatly appreciated! Also, more ships are coming.

15 cm长老式明轮船。需要用到胶水！！！如果用PLA打印的话，502就行。此模型不需要AMS。船能浮在水上，轮子也能转动。灵感来自于一艘明轮船小学劳技老师送我的，现在想复刻一些童年回忆。之前的集装箱船也是这么来的。

船壳里面可以加上两条细橡皮筋，步骤请参考下面的组装指南。这样反向转轮子后松手轮子就会自己反转，类似于发条玩具。我亲测放松开轮子船能在水上前进25 cm，不过距离取决于橡皮筋的长短，粗细，和松紧，加上放开前转的圈数。

下方是组装说明。我已经装了3遍了，应该没大问题。希望各位大佬能留下建议或想法，求打分和评论，谢谢！尽请期待下个船模。
