This is a model I just finished for a friend making a Batman Forever display. He requested that the file be the extended, "ready to shoot" spear as opposed to the more compact version.
Thank you! There isn't a huge amount of reference out there, but after a few eureka moments over the past few attempts, I was able to work out the unseen parts. Test prints coming soon.
Thanks again for the new reference!! You seem the be the man with all the links I can't find!!
I have the carabiner modelled so I can make the changes to the grapple. I must change the grip now also. I spent today working on the Pipe grabbing grapple. This video will help with that big time also.
