Tri - Hex Clamp

thingiverse

This is a clamp designed primarily to uniformly apply clamping pressure to 3 or 6 sided workpieces. It uses 1/4-20 captive nuts and 3 1/2 " long fully threaded hex bolts. The design includes small clamping feet and a knurled knob to turn the bolts into a very comfortable to use thumb screw. Two of the assemblies have proven to work very well when used on both ends of blanks for end grain cutting boards, with 3 standard F style clamps across the flats in between.
