Computer-Aided Design
TinkerCAD
We assembled the original Open PCR machine using TinkerCAD. We placed every part and used the tools to align them and produce the final part using all the pieces. Then, we changed the color to our taste. We decided that the size was an issue because we wanted it to be portable. As such, we made the machine smaller using the transformation tools, and so it is portable.
Our Design
We chose this design because we liked the colors; we placed the fans and heating system near each other (near the vents) for better cooling. We put two fans and two heating systems as well as a larger power source to power it more efficiently. The size of the machine was reduced in order to make it portable and convenient.
