Increase wood thickness of a model

Hi, I built a furniture with a wood thickness of 15mm on sketchup, but now I realized that using a 20mm wood thickness is better for stability, is there a way in sketchup or using a plugin so that I can change that thickness value and have the model resized? or do I just have to recreate everything from scratch, thanks guys

It might be possible but it depends how you built it in SketchUp. If you share the .skp file we can surely give you some ideas about how to approach fixing it.
