Head replacement for ProGrip clamps

This is a replacement 90 degree head for the Pro Grip clamp system. My original broke and they are no longer sold here in the UK.

I have shortened this one to 145mm wide so that I can print it. It should be straight forward to make this wider if needed. If there is any interest I will create a wider design and publish it here.

Added a 185mm wide version for those that have a larger printer than me.
