Tincture display - holder - multiple sizes

I made a few different display models and sizes. This one is for the 4 height in different widths. Need 3 or 5 heights, check my other files. This way you can make it as modular as you want. The cut out diameter is 39,5mm so it can fit most 50ml bottles or smaller. There is 20mm height difference between the floors. Total length is 171mm and width 42mm for one width. Let me know what you think.
