ISO-compliant thumb screws，Tighten and loosen by hand without theneed for tools.Optimized according to the characteristics of 3D printing.Because screws below M3 do not have sufficient strength for 3D printing, only M4-M10 screws are designed.also designed flange nuts ,The flange distributes pressure, so youdon't need a washer

To ensure better accuracy and strength, please use a layer height of 0.12mm or less and reduce the printing speed.

Generally speaking, PLA has better rigidity and is not easy to deform, while PETG has better toughness and is not easy to break.

Each filament has a different shrinkage rate. Before printing, it is recommended to try printing a sample test and make appropriate compensation.

Thread Pitch：M4=0.7mm,M5=0.8mm,M6=1.0mm,M8=1.25mm,M10=1.5mm

符合ISO标准的翼形螺钉，无需工具，用手即可拧紧和松开。根据3D打印的特点进行了优化。由于M3以下的螺钉对于3D打印而言强度不够，因此仅设计了M4-M10螺钉。还设计了法兰螺母，因此不需要垫圈防止松动。

为确保更好的精度和强度，请使用0.12mm或以下的层高并降低打印速度。

一般来说，PLA刚性较好，不易变形，PETG韧性较好，不易断裂。

每种耗材的收缩率不同。打印前，建议先试印样品测试，并进行适当补偿。

螺纹间距：M4=0.7mm,M5=0.8mm,M6=1.0mm,M8=1.25mm,M10=1.5mm
