Note:the kit no including the printparts Based on two legends: the Klicky Probe by JosAr and the Euclid Probe This design attempts to replicate Klicky as closely as possible using a PCB-based design, to try and achieve the following aims: 1.Reduce the problem of magnets working lose or seating poorly in printed parts 2.Increase the current being switched, which might possibly result in a longer switch lifetime. 3.Add LEDs.
