this is a strap wrench tool i created in my job i use carabiners alot and the screw locks are always getting stuck so i created this easily loosen them up there are many other uses to as its adjustable can open bottles tighten and loosen bolts and also plumbing pipes too

i printed the main grip in petg and the strap separate in a medium firm tpu

the small wedge locks the strap in place in the front hole fit this tight ant the lead is fed through the second hole pull hand tight then just twist the grips should grab the strp useing only the force of its self i found this tool super handy and hope you do too

just use supports buildplate only but coul getb away with no supports
