I'm sharing my personal collection of 2D Uniform Boxes.
The resolution used is 730x730 in .png format. Some images may be distorted, but I tried to leave the best shape and if you want, just give resize.
I also made use of Photoshop to correct the images and did many that I didnt find on NET.
Some images were in horrible resolutions 240x180 or smaller, so as soon as I thought I'd better update here
May have some duplicates or variants.
I hope it will be useful for you. Will share all the systems I have.
