Bed leveling tool for Ender-3 S1

I watched this video and try to make my own one for the Ender-3 S1: https://youtu.be/b5gFWDcmWBw

I redesigned this specifically for the Ender-3 S1. Also I included a Step file in case you want to make it fit your own printers.

原本固定噴頭模組的中間兩顆M3需另外用兩顆較長的M3x10來代替，把這組裝上去

另外需備三顆M2x6的螺絲，用來作轉動關節，注意，能打磨到剛剛好能轉動是最好的

這個設計的精確度完全取決於連結之間的虛位控制得好不好。
