Obsolete Page
The subsets have been replaced by kits.
The Structural subset is partially superseded by Structural Kit.
Description
This subset includes over 50ft of 1"x1"x1/8" angle, with 1/4" holes drilled at 1" intervals and cut to lengths from 1" to 24". 10-24 fasteners included in the subset are used to attach the angle pieces together, with room for adjustments. Several captive nuts with 2-3" 10-24 screws can be used to clamp things to the angle structures. This is the foundation subset used for building static contraptions, such as test stand, bot frame, holding jig etc.

Note: the BoM is arranged and the vendors are picked to minimize the total order cost. Some vendors happen to have affiliate programs in which we participate. For us this is one of the ways to raise money for the project. For you, there is no added cost. If you come across a significantly cheaper vendor, please let us know.
