Customizable organizer storage Box

I wanted to play around with OpenSCAD and this is the result - a somewhat customizable storage box. There is an option for cut-outs to save material. When utilizing material savings, ensure that the printed bars (see “d” in “Savings”) do not become too thin, as this may cause them to vibrate during printing and reduce print quality. A higher wall thickness, slower print speed, or smaller cutout size (see “a” in “Savings”) allow for smaller bars.If “a” is greater or in the range of height/ depth/ width cut-outs will obviously not generateWhen using the maximum width/ height/ depth make sure the wall thickness is increased/ print speed decreased, otherwise there might be a chance of quality loss as described in 2.Some input validations are in place (if your input is invalid it will show an error message - for example: “cut out diameter” has to be smaller than “height"). This is my first time coding in OpenSCAD and some features were added on the way - but it works well enough for my
