make a mini base plate. Basically like a c-channel with the two ends of a rail.:o
How small? What size would you want it? What would you use it for?
like the length of your average c-channel and the standard 2 holes(technically 3) wide. Also I suggested this because a lot of the time I need a part with the 2 sides that a c-channel has but I want to attach it at the ends. I am able to do this but it requires me to waste my bars by cutting off little to bits and bending them.
Maybe a corner bracket similar to mcmaster 1088A31
