Updated the adjustment bolt mount by lengthening the bolt arm by 2 and 4mm and threaded the bolt hole for M3.
Micro adjustable Z-stop for the Creality Ender 3 and similar printers. Only required additional parts are ~1" square piece of 3M double sided sign tape and 1 bolt. The switch bracket is designed such that the T nuts in the channel will not rotate when aligned with the mounting bolt. This prevents the T nut from rotating when the bolts are tightened to the frame.
