S.T.E.V.E PSU safety box remix

Currently in the process of building C.R.T's S.T.E.V.E CoreXY 3D printer. From the start I decided to customize my build slightly and one tweak was to maximize print area with the specified width and depth of the stock frame. The stock psu safety box is designed so it would sit almost completely within the frame however this interfered with the bed gantry in the configuration I currently have it in so it was time for a remix! Please note that you will still need to print the original lid fil
