Some update on the magnets. I had to replace the first magnet because I needed to elevate the bits some more to be able to use the system effectively. (Short note on magnet remowal. Apply a drop of super glue on the magnet, push in a screw or something wait 10 seconds then pull, and you have your magnet removed

because other methods may damage your nerves or your magnet).
So I bought some neodymium magnets. The diameter is 6mm, the height is around 7 mms. (I ended up using 8,5 mm). It is very strong and it works very well. Easy to pull out standard 1/4 “ bits.
There is one downside to this mod: I csnt use the bit holder with Leatherman bits anymore. Unless I remove the magnets. But I wont need to do that. So thats it. I hope this story might help someone.
PS: the longer reach negates the off centerness of the bit driver, and it is much more convinient to use than the bit driver without the extender.
