Harbor Freight Ratcheting Bar Clamp Connector
thingiverse
This is a small piece that allows you to connect two Harbor Freight / Pittsburgh ratcheting bar clamps end-to-end to make a clamp that is twice as long. Uses the bolt that connects the factory end piece and a press fit M6 nut. I printed with 2mm walls in PLA and 20% infill and cranked down on it as hard as i could, it was fine. The pictured version allows a fair amount of flex in the clamp. I believe the long version will fix this, but it is untested (too big for my tiny printer). Please report back if it works.
