litho lamp back panel with switch

being the back of the lithophane box is typically not visible Created some back panel's to accommodate the lamp without having to print an additional litho that would not be seen.
created litho panel v2 switch for lithophane lamp v4/v3 by GrkManga, with a slot to add a rocker style power switch to turn the lamp on and off, I purchased these switches on the amazon link below
