I was able to get 1/4" spacer for single gang electrical boxes but not for a triple one. Is split in two so you can fit without dismantling wiring (just switch off at breaker box). Allow you to tile around box without the receptacle of switch being below the faceplate. I designed for a resin printer and was able to lie it flat directly on the platform as it is neither large in area or in thickness. Prints in about 25 minutes on my Jupiter.
