The potionmasater refill rack was a quick laser-cut design I threw together the day before the party. I figured I could use some helping hands to hold test tubes as I refilled them throughout the party. Bonus for having marked refill lines to measure against.
This is one of those good-news/bad-news situations. The good news is that it generally worked. The bad news is that the design was a little loose. I should have either tightened up the holes for holding the test tubes or spaced them further apart. The other bad news is that the 2oz marker line was incorrect.
But overall, it was a quick little design that turned out to be absolutely valuable that night.
The laser design files are available on the GitHub project page.
