Microscope Slide Holder (22 numbered slides)

Should handle 22 slides at 75mm x 25mm x 1mm.
The model is 74.36mm x 174.5mm x 9mm

Edited sztech's design in tinkercad to be more organized. I have a color coded book system to keep track of slides based on color of slide holder.

Let me know how it works for you and your improvements!
