Thanks for the tips, I really appreciate it! I like the idea of standard slot sizes. Someone posted a case they had cut, and their tab/slot design was really confusing for me to follow.
He'res the link to that thread, you may find it interesting...
Wow I love how these turned out, they look super professional.
I am thinking of designing a case to be laser cut and assembled later, but have literally no experience with cad/sketchup. do you have any suggestions or tips?
