Yet another Ender3 tool holder. . .but this one works for me.
Leaves the tools handy but 'out of the way'.
Relies heavily on:-
Precise Customizable Extrusion V-Slot Covers | 2020, 2040, 4040 | Ender 3 compatible
by Crabiter June 09, 2021 . . .for its attachment to the printer. An excellent piece of work, and one that I couldn't emulate.

Suggest printing upright with the plier holder flat on the bed,.using supports rather than attempting to print on its side.

Holds all the tools that I used for construction, except for the screwdriver, which I did not needed.

This will work on .3 extrusion, but it jeopardises the strength of the attaching clip.
