Coffin case

Hello, Please be gentle this is my first ever creation, I am in college for Mechatronic engineering so I have a good amount of supplies. This helps keep me organized in school and on the go, I made one on my X1C which is just this file at 100% and made one on my a1 mini at 84%. Please don't forget to provide supports if my file does something wacky. I used Sunlu transparent red and Poly Lite matte black for the photos but you can get as creative and spooky as you want with a coffin. Just remember to scale the lid and container together for perfect fit. There are 2 of the pencil holders, one with the ghost and one with out.  the lids are also interchangeable if you do not want anyone to see inside your coffin. I appreciate any feedback again my schooling also requires me to do CAD classes so any feedback is helpful feedback for future projects.
