Test tube rack
thingiverse
The human-sized robotic arm holds at least 28 test tubes, each measuring 5.5 inches in length and 13/16 of an inch in outer diameter or less. Due to its massive size, I broke down the parts into smaller components that can interlock together seamlessly. A small amount of glue on the joints would enhance stability even further. Since I haven't printed this design yet, please let me know if you'd like to try it out first-hand and share your feedback. I've included the design file for anyone who wants to customize or modify it as needed.
