Elegoo Mars Storage Box E-003

I'm still new to the topic and I'm trying out a few things.
I was surprised that I couldn't find a .stl file with which I can print a box for the tub with my printer. It seemed absurd to me to have to buy another printer for this. I now have two liters of resin and have spent three days printing this version

1. Printed cleanly and straight away.
2. is uncomplicated and the most important
3. can be printed by my Elegoo Mars 2 for Elegoo Mars/Mars2/Mars2 Pro
   The first two attempts were rather poor.
   Since I was running out of gray resin, I asked myself what would happen if I just pour black. That's the result.
   A "colorful" tub, for storage and cleaning, in which the bottom of the tub floats. Both sides are glued with superglue and with rubber bands I let it dry overnight. It's only the 003 version. I might come up with a clever locking mechanism in the following versions
