Modular Dice Tray

I like having my dice all lined up during ttrpg games, but sometimes I have to move the sets from one place to the other to open space on the table for miniatures, notebooks, cards, etc. I keep getting distracted by reorganizing the dice over and over again, so I decided to design a tray to hold each set, and made it magnetic so I can combine lots of modules depending on my needs. Hopefully this can help improve your games too :)

At its original size, each tray is 18x4x2cm and it comfortably fits standard sized round and sharp edge polyhedral dice sets. It has six 6x2mm insets for magnets. I personally used 5x2mm magnets so I would have a bit of spare room to fit them.

This is my first design, so feel free to give me advice on how to improve future ones. Also please excuse my poor paint job and decor lol
