Dracula Drone

*Designed to be made using FDM without the need for support material. *Primary material in mind was white ABS, however, the design should be compatible with almost any plastic FDM material. When an organ donor arrives at the hospital, a number of tests need to be performed to ensure compatibility with the recipient, however, not all of those tests can be performed at the hospital. This means blood samples must fight through city traffic to an offsite lab, before any procedures can begin. Having relatives involved in the medical and organ transplant industries, I learned that far too many organs are lost during this process. With the Dracula Drone a hospital would be able to easily attach the blood samples under the arms of a multi-rotor and quickly send them away to be tested. For the purposes of maintaining the balance of the aircraft an even number of samples symmetrically arranged front-to-back and side-to-side is recommended, though the limit of how many samples could be carried would only be limited by the number of arms the drone had (whether it be a quadcopter, octocopter, etc.). The 3D printed rack serves as a test tube holder, a protective cover, and a cooling device. Cooling is accomplished through the use of prop wash cooling, something that hobbyists use to keep the electronic speed controllers (ESC) from overheating. Additionally, the design is shaped to channel and constrict the flow so that it accelerates down the length of the test tube. A simple printed tab slides down into slot to keep the test tube from falling out, which in turn is kept in place by being pressed against the bottom of the drone. The rack is designed to be light weight, easy to install through the use of zip ties, and not require any support material. This ensures a single, light and durable piece, which cannot be replicated through conventional manufacturing methods. Updated (8/27): To provide supplementary cooling, molded cooling packs (whether they be ice or dry ice etc.) can be
