Dremel Welder Adapter (17mm holder)

thingiverse

i modified the original design to fit my welder, which has a 17mm handle bar (foam wrapped so it has some flex to it)i designed it with a bit of a flex clamp. the bigger hole accepts a M3 x 4 x 4 insert, and the other hole is 3.2mm to allow an M3 screw to pass through, which acts as a clamp once the welder is loaded.however, I ended up just using a clamp :) much easier and strong enough for the operation.
