Techniques are disclosed relating to modifying packet data to be sent across a communication link andor bus. An inflatable tubular support having an upper portion with a first radial outside diameter, and a lower portion with a second radial outside diameter that is greater than the first radial outside diameter, is coupled to the platform by a fastener. Dimensions of the processed sample are compared with the provided data to identify differences between the structure of the processed sample and the structure of the three-dimensional microstructure design.
