Microscope slide box for 61mm slides

The original design was great but it unfortunately wouldn't work for me because I have a bunch of slides that aren't the standard size ([these ones to be exact](https://www.amazon.com/dp/B07GRN4H38)). So, to make this work with my collection of 61mm slides, I just made the box and lid narrower. I also lengthened them a tiny bit because these plastic slides are just a hair thicker than glass ones.

I don't imagine there will be much demand for a box with these particular dimensions, but I wanted to share my remix anyway on the off-chance that it might save someone a bit of time.
