Fluidy resizable box using inkscape live path effect
This is a box designed for a laser cutter where you can click and drag to resize the box. It's implemented using a little-used inkscape feature call live path effects. It's designed for 3mm thick wood. As you resize the box it will automatically resize to have the right tab depth and will also change the number of tabs to something appropriate for that size.
The primitives I used to build this are on the "primitives" layer. You can modify those primitives to work with different depths of plywood.
You can't group the objects or else the live path effects will stop updating.
