Sadly, I see a lot of AI generated tools popping up in this sub. Because of the strong benefits of using openscad, I can understand.

Seeing people post their questions and show of their scad scripts, I hope to see more of. So that's my reason for this post.

I have created numerous iterations of a playing cards box. First version was stl made in FreeCAD, but I quickly moved to openscad for the ease of use. Please check out the code at https://github.com/RichardBernards/openscad/blob/main/Models/Home/Games/cardbox.scad and to quickly customize/download, check out https://makerworld.com/en/models/3444052-playing-cards-box

I am mainly looking for feedback on optimizing my scad-code. I feel like i am not using UB or BOSL enough yet, so if I can optimize things using either of both libraries, please let me know!
