We have designed each component of PCBGRIP to ensure all the components not only work individually but also in unison. Careful consideration was given to the physical dimensions of one part relative to the other parts and relative hole locations to maximize the number of combinations in which all of the parts can be used together. Most parts have 3mm holes and common M3x0.5 threads. There are countless ways the parts can be connected and used together - limited only by your ingenuity! The red components in the videos and pictures are CNC machined from 6061-T6 aluminum, anodized, and laser engraved. Hardware is stainless steel, with the exception of the large brass thumb screws.
