3/8" Rope clamp

I have a 35lbs puppy who loves to be outside.  Until I come up with a better solution, I have been tying him to a tree with a 50'+ tether.  He seems fine with this but he is a puppy and has a tendency to chew through things… like ropes.  

Sure I could tie the rope to the snap hook and call it a day but whats the fun in that?  I had a few m5x16 screws laying around so I modeled this up around that as a quick fix.  It's crude - but it works - at least for the puppy.  

This was designed for the 3/8" Diamond Braid Polypropylene Rope available at Home Depot. 

This should go without saying but - DO NOT USE THIS FOR MOUNTAIN CLIMBING, SPELUNKING, OR ANYTHING ELSE THAT COULD BE LIFE THREATENING.
