This device simulates a pair of pliers, vice grips, etc. used specifically for the removal of 22mm RDA's, Tanks, RTA's and the like from a device they might be stuck on.
Simply put it takes the hassle and destructive behavior of a pair of pliers out of the equation (rips, burs, dents, creases), if something is stuck on your mod.
Use is pretty intuitive, Put your pointer finger in the ring hole, then your thumb on the round edge opposite the ring hole then place the open hole over an RDA near the base, squeeze the two sides together and rotate in the direction to loosen it and the RDA or tank or whatever should come off fairly easily.
Please only print with strong and flexible plastic as this is a tool which is made to flex for effective operation.
Update: V2 - Finger handle upgraded with a beefier stem increasing load tolerance V3 - Entire structure was made beefier, Vertek Logo added, thickness increased 1mm V3 Smooth - Version simply with smooth edges to make it more comfortable in the hand
