This is a remix of some flush cutter handles i found on thingiverse (those: https://www.thingiverse.com/thing:4802229 ), i modified the base of the grip to make it a bit shorter. They are made for the flush cutters that you get with most creality printers and most printers in general im guessing.
Printing:
You need to print the model twice, it fits on both sides, I recommend laying the flat base of the handle (the one with the hole) against the bed to make it print properly, I printed them in pla and they work just fine, I would recommend using a flexible filament if possible to make them a bit more confortable. No supports are needed.
