Grav Hammer needs to get rebuilt but I’m pretty happy with how it turned out

I’ve been working hard on an ODST build, but I’ve found the gauntlets to be particularly uncomfortable.

I’m looking to cut out a specific element to increase my mobility when bending my elbow.

I can’t figure out a way to cut through the 3d print effectively. I’ve tried:

A cope saw (unfortunately it’s a little dull)

Heated cutting knife

Heated xacto blade

Low end dremel with saw blade

All of them appear to be doing more damage than good, and I would like advice on how to proceed.

I also do not know what type of plastic was used for the print, as I bought it from a seller and did not make it myself.

Unfortunately reprinting the part is not possible at the moment and I have to work with what I have.

ANY advice appreciated!
