Upgraded and optimized the old version of the pinball game, adding obstacle accessories and springs. For those who do not have hardware springs on hand, they can be replaced with springs from the first plate. Note that springs cannot be printed with PLA as they are prone to breakage. It is recommended to use PETG for springs, while PLA can be used for others.
The printed spring does not play as smoothly as the hardware spring. I suggest buying a spring instead. The specification is 10 * 50 * 0.5

升级优化了旧版的弹珠游戏，增加障碍配件和弹簧，手上没有五金弹簧的可以用第一盘的弹簧代替，注意：弹簧不能用PLA打印，容易断，弹簧建议用petg，其它可以用pla。

打印的弹簧玩起来没有五金弹簧顺滑。建议还是买个弹簧吧。规格是10*50*0.5

以下是部分组装示意图：

这一步要用胶水把跳板和圆柱粘紧。

弹簧请对准模型突起的小圆柱

这一步最后要用耗材线固定
