SN04 Z Adjuster remix

I remixed this because i could not obtain the same hardware as was used in the original. I got a bag of assorted springs from princess Auto. I had some M3x45 bolts in my spare bolt kit. and extra M3 nuts from the Printer kit. The spring was about 6mm diameter by 40mm uncompressed,

On the front piece that holds the sensor I added ( subtracted) a slot 8mm wide by 10mm deep to accommodate the compressed spring if needed. I changed the round recesses for the sensor mounting bolts to 5.55mm h
