I remember reading in here somewhere about a site or script etc which you could add your print items and it would run an algorithm to fit as many objects into your board size as possible.
If this rings a bell to anyone could you help me find the site?
Just FYI, I used the deepnest scale conversion for Inkscape. The final nests however changed the measurements of my objects by just a bit. So if you do use it, make sure you double check your object size after it’s done.
