Z Axis Endstop Holder For Mech Endstop v1.2

Endstop: Mech Endstop v1.2
Needed a simple endstop holder for the Z-axis that won't move at all and can be tightend a lot.
I'm not very fond of the snap-ons or one sided screw options, mine broke in a attemt to recalibrate it for the 11th time-becasue of the lack of created friction

Made for M8 rods and M3x20 [mm] screws.
The first block has 4mm holes wich allows the screws to travel into it freely, but the end block has 3mm holes wich makes nuts unneseccary, works easy and feels sturdy.
