X-Carve X carriage Hard Limit Switch Holder

i made this to hold a second micro-switch on the X carriage of the Xcarve so i get the normal homing + hard limit because i use GRBL and you can connect both in parallel

i male use of the 2 unused M4 holes that are aligned with the homing micro-switch

Need :
2 M4 12mm to 14mm
1 MicroSwitch
1 M3 Tap to enlarge the microswitch holes
2 M3 8mm to 10mm

(my micro switch holes are 2.4mm so i can use the tap on it , dont do it if you have different micro switch ; also if you do it , verif
