Wood burning tool tips tray

Wanted to make a tray to keep the different tips that came with a wood burning tool I had ordered on amazon. Took somr trial and error but this one works pretty good. Made it a sleeve as well to keep everything together. Hadn't got good enough to add a latch or a stop to keep the tray inside the sleeve so using a piece of tape at the moment. First time really doing anything this detailed in CAD and using Fusion 360. Any pointers or feedback would be great.
