The original tool rig is really good! But I do not need the holes for the hex wrench however something for my countersink tool. So I moved the forceps to the left and put a hole together with two very small lips at its original place. I use this model --> https://www.amazon.de/Handentgrater-Werkzeugsatz-Entgraterklingen-Gratentferner-Aluminium-Kunststoff/dp/B07DH5M1J6 which is sold worldwide by using different brand names.

I had to finish with sandpaper a little bit because the handle of the tool is a little bit thicker in the middle than at the end where it needs to hold in the lips. But making the hole bigger in the design let it fall down in my case.
