About this 3D model

I put new (thicker) tiles on the kitchen wall and the spacing between the fixture and the wall enclosure got to small. The spacer fixed that problem. I created 1mm, 2mm and a 3mm versions of the spacer. The spacer is for a 68mm diameter electric box. The Sketchup file ending in "flat" is just that, so you can create your own fitting spacer.
