MK8 extruder mount for I3-RS 3d printer

Mount to adapt MK8 extruder in X dolly of I3-RS 3d printer, there are 2 versions for 12mm inductive sensor and 18 mm capacitive sensor. The sensor that im using is a 18 mm diameter,12 V capacitive sensor LJC 18A3-H-Z/BX its a NO (Normally Open) NPN sensor with 10mm of detection. To make it work properly with Makerbase 1.6 was necessary build a subboard PCB. This sub board is for sensor and to rgb led transistors. The board uses a 1n4148 diode, a 10kohm resistor and three NPN 2n2222A transistors
