[Mechanical] Initial Design Printed

The initial design was printed on the rapid prototype printer. Already, we know that we have some changes to make such as with the dimesions. The 1.75" x 1.75" outside dimensions have to be modified to fit within the 1.25" constraints. The base contains a square outside to allow maximum area for securing to the backing plate. There is a 1/16" o-ring race around the outside and another around the axle shaft. This will allow the compartments to be sealed off. The five compartments allow for four altitude-based samples to be collected and one baseline sample.

The top has a cutout to allow for one open compartment at a time. The servo will rotate the top disk at the desired altitude allowing the aerogel to collect samples. 

This is how the assembly will look put together.
