besiege Siege catapult

steam沙盒游戏围攻，通过各类模块建造自己的机械通过关卡，我尝试复刻了几个基础的模块，建造了一台中世纪攻城投石机。一些组装注意事项：1、销子我预留的0.2mm间隙，需要根据打印机和材料调整。2、销子配合合适可以不用胶水，以便模块二次拆除利用。我组装好无胶水。3、轮子和轴承的滚柱因为打印粘接，组装前需要活动一下，才能顺滑。4、皮筋我用的孩子绑头发的皮筋，如果想要更好的性能可自行替换。 In the Steam sandbox game Siege, I built my own machinery through various modules to pass levels. I tried to replicate several basic modules and built a medieval siege catapult.Some assembly precautions:1. The 0.2mm gap I reserved for the pin needs to be adjusted according to the printer and material.2. The appropriate combination of pins can eliminate the need for glue, making it easier for the module to be dismantled and reused. I assembled it without glue.3. The rollers of the wheels and bearings need to be moved before assembly due to printing adhesion in order to be smooth.4. I use a rubber band for tying children's hair, and if you want better performance, you can replace it yourself.
