I’m trying to model something for 3D printing for a change. It’s a box for smarthome switches. Everything worked out fine so far until I exported the first ready draft to STL and checked it in the slicer. I made the walls of the box way too thin. The way I created the walls was with the solidify modifier - which I for some reason applied - so no changing params any more… Is there an easy way to increase the wall thickness or is it deleting all inner faces and solidifying again?
