About this 3D model

What started as a simple idea to organize some of my game carts turned into a passion project the past 3 days to have a modular cart oganizer. In part this was brought on that the existing cart holders I found either didn't hold enough carts or too many. Also they seemed over designed. One N64 holder had 4 spots and Cura gave it over 24hrs to print. Personally I wanted a streamline system that was fast to print, modular and strong. Also if I add a cart to my collection I could easily print off the needed piece and just add it on. The three cart organizers will connect to each other if you want to mix your games. For example group all Zeldas together for a display.
