Squeeze Fan - 挤压风扇

What makes this squeeze fan unique? This squeeze fan uses a printed ratchet and spring to allow the fan blade to spin (mostly) freely without forcing the movement of the squeeze handle.     All parts are 3d printed, except for two M3 screws and one nut.     Print 3 x Peg, 1 of everything else. Inner ratchet piece I recommend you print with supports. No other parts should need supports, although you could for the screw hole in the Bottom Frame. Infill: I used 10%, higher should be fine.     M3 Hardware: 1 x 20mm Screw 1 x ≤ 15mm Screw 1 x Nut   Assembly: (suggested order) Insert axle upward into bottom frame Insert the two middle pegs Ratchet gears onto peg Middle gear onto peg End gear onto axle Handle spring (Make sure the spiral is pointing downward, or the outer corner of the spiral facing right so the teeth line up) Peg for handle Handle (Place between gears in extended position) Top frame Screw and nut through spring hole Fan Screw through fan into axle 这款挤压风扇的独特之处是什么？ 这款挤压风扇采用打印棘轮和弹簧，使扇叶（大部分）可以自由旋转，而无需挤压手柄移动。 除两颗 M3 螺钉和一个螺母外，所有部件均为 3D 打印。 打印 3 个挂钩，其他所有部件各 1 个。 内棘轮部件我建议您打印时使用支撑。其他部件不需要支撑，但底部框架上的螺丝孔可以。 填充物：我用了 10%，更高应该没问题。 M3 配件： 1 x 20mm 螺钉 1 x ≤ 15mm 螺钉 1 x 螺母 组装：（建议顺序） 将轴向上插入底部框架 插入两个中间销钉 将棘轮齿轮安装到销钉上 将中间齿轮安装到销钉上 将末端齿轮安装到轴上 手柄弹簧（确保螺旋线朝下，或螺旋线外角朝右，使齿对齐） 手柄销钉 手柄（置于齿轮之间，处于伸出位置） 顶部框架 将螺钉和螺母穿过弹簧孔 风扇 将风扇螺钉穿过风扇安装到轴上
