It is just a remix of a great tool made by @8link (https://www.thingiverse.com/8link). I just decided to use drill bits instead of allen keys, because it is cheaper way :) So, just print the model and insert 3mm-3,2mm drill bit into the holes. keeping ~5mm outside. Dril help may be needed, just screw it slowly. Using this simple tools you can disassemble the front fork of your ES1/ES2/ES4 easily. Hope pictures are enough informative.
