Multi-Bit screwdriver (box only)

I am an undergrad student and complete beginner in SolidWorks. And as a real-life inspiration (Photo attached) for assembly I recreated a screwdriver box. Though I have only made the box, I plan on adding the screwdriver and the screw heads later. Please note due to lack of proper measuring tools, all dimensions are approximate. I had no experience with rendering [nor do I have a capable system to do it :( ], so the renders came out bit crappy. I also faced difficulty in producing the circular pattern of the lofted groove at the bottom [It's still unsymmetrical :( ]. But just putting it out there if you guys can help me out. Modify it as you like and feel free to ping me about my mistakes (there might be a lot!).
