I would be happy to but I didn’t save it. I make them when needed.
It’s just a couple of rectangles with rectangles of the stated sizes added using union or subtracted using difference (Inkscape terms) - draw a larger box, draw the small ones in desired test sizes, use the align feature to get them on the edges, then the appropriate boolean command. Add text if you like.
The slots and holes piece was so I could check how wide (the smaller dimension) they needed to be to get a nice edge for corners, and a secure perpendicular joint for inner parts. As all my slots/holes were 5mm, the tabbed piece was so I could see the best length for 5mm long slot or hole (turns out to be 5.2, which means the kerf for this material is 0.1mm) and also the best depth/width for the tabs to give nice corners or a flush finish when inserted thru a slot.
I don’t use “box generators”, I prefer to test the material I’m using, then make my own slots/notches/tabs using the apps additive/subtractive technique.
