About this 3D model

I thought it would be fun to create a few different Lego style keychains. I started with creating 2x2, 2x3, and 2x4 (both normal and thin) verisons. If you have any other versions that you would like, please let me know and I can see what I can do! Also, I have not printed these personally. I did use given dimensions of a Lego brick found online as well as using calipers to measure the Lego bricks, but if there are still any issues PLEASE let me know and I will fix the file.
