Strut Channel Caps

We needed some caps to cover the ends of some electrical strut channels around the shop so I designed these. StrutCapInternal fits inside of a standard 1.625" strut, StrutCapExternal1 fits on the outside of the same size channel. StrutCapExternal2 fits over a smaller size channel. Using my Printrbot Simple Metal I can print the externals without supports, the internal one support will be required.
