Spreader clamp

I needed a spreader clamp to fit into a channel to position a window rubber gasket till the glue set. I couldn't find what I needed anywhere either commercially or as a printable. So I came up with this and it did the job. The part is reversible so print two for each clamp. I used 5mm hardware for the hinge and the tensioner. I'd use ABS or Pteg at high infill to get decent strength.
