Interlocking dovetail-sided box for small 1/2 oz. eyedroppers and 15mL e-juice bottles

This is a little interlocking design I made to organize a collection of small homemade Sriracha eyedroppers. I was inspired by another design I saw recently on this site and decided to make my own to suit my purposes.

I designed this as a "cheap" design I could use to calibrate my machine as well as be something I could print over and over, and not mind having too many extras.

The interior hole is designed to be a bit wider than 1" in diameter, and 7/8" deep. The overall size is about 1"h
