CR-Touch Cover

I designed the cover for the CR-Touch because it goes into error mode if you get too close to it with a PI-IR cam. it seems that the Pi-cam's IR lights are crashing the CR-Touch. the cover prevents it from going far. At a distance of 1 cm between Pi-IR-Cam and CR-Touch, it still jumps into error mode. but in everyday use and printing, it is unlikely that cam and touch will come so close.
