SP binding replacement toe strap

I tried to print it with ABS, but unfortunatly it broke in the cold weather, but it can still be a temporary back up strap. 

Maybe you can try with higher quality Filament, like Nylon, Tpu(may be too soft). 

SP固定器前绑带

用过ABS打印，不太行，低温会断，当个临时的备用绑带害行。

实在不行你们用别的耗材试试，尼龙、tpu啥的（不过tpu强度可能不太行）。
