Sparkfun just announced a neat tool but although it is 3D printed are not sharing the 'source code' but only selling the finished product for $ 3.95 USD. The shipping would make it a LOT more here in Canada.
I do not have the skills to recreate this, but maybe one of our members does. Take your best shot and post the stl file back here when you have it ready.

My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

These are pliers, right?
What is the name of the connector? it's a type, I think. Also, don't they come different sizes, 2 wire, 4 wire, stacked, etc.
The one who has the most fun, wins!

Addendum:
They're JST connectors.
I'm working on rebuilding my poor electronics vocabulary.

@tfmccarthy JST the pliers are for the LiPo bag batteries common on many small devices, I probably have 4 or 5.

@tfmccarthy Here is another solution and it would be easy to make these for each size of plug https://www.tindie.com/products/kdcircuits/5pcs-plug-puller-jst-ph-20mm-2pin/

Maybe this will do the job although it works in a different manner. The zip file contains an OpenSCAD script with parameters to allow custom-making a sort of tweezer-like device to grip the JST connector top lip allowing it to be inserted or extracted from a PCB. This script allows the user to specify leg length, width, height and the gap between legs (to allow for the wires in the JST connector).
Print two of them, turn one over and join them with an M3 bolt and nut to form 'tweezers'.
Two STL files are included in addition to the script (all measurements in mm)
a) leg length, leg width 8, leg thickness 8, gap 6
b) leg length, leg width 10, leg thickness 6, gap 6
Hope this helps
Anything seems possible when you don't know what you're talking about.

@will This one is a lot better I think in terms of getting into tight spaces especially if the arms are tapered.
