Here's one I built based on the
Thingiverse file by SentinelProps. I used the
remixed one by Astrogames and modified it a bit further to decrease the depth of those several thin grooves around the rectangle in the silver section - they were deep enough that support material was hard to remove cleanly. The original files were hollow and perfectly sized for a wooden dowel to provide alignment.
The base file deviates a little from the design in the game -- the original artist seemed to only have that promotional art to work from -- so I didn't hold too closely to the reference when detailing the exploded end. Looking at it again, the torn/burnt grip end could use a bit more grime/charring, and I'm thinking about shortening the wire mess...
