Gillette Labs Case

This is my first project, Gillette Labs Case with 2 blades slot and honeycomb lid. The project is lightweight ( 89g ) . The razor fits perfectly in the box with ease. I also designed some lockes that will allow you to not make the lid fall and keep it attached to the box (gently push them in the back corners of the lid and they'll secure the lid to the box)   Any critics is welcome, how can I improve the model? I'd love to learn from you!
