Among Us Deck Box

It should fit 100 double sleeved Magic cards comfortably as I based the inner dimensions on an Ultra-Pro Satin Tower. The image I have included is a 100 card single-sleeved deck with a bunch of tokens and it fits very nicely.

The top and bottom slip right together with .3mm tolerance on each side. It's not a tight fit on my print, but it's fine for what I'm going to use it for. You could add little semi-circle nubs and indents to make it a tighter fit.

When I scaled up the figure, the polygons are much more visible, but I kind of like the way they look and I might end up sanding and painting it, so they don't bother me. If you want it to print smoother, you'd have to find a way to increase the polygon count in a program.
