Batman the Animated Series - Mr. Freeze Gun
Batman the Animated Series - Mr. Freeze Gun
Gun created based upon the Batman - The Animated Series freeze gun that Mr. Freeze uses. Not perfect, but it's a good starting point for someone to jump from.
If you downloaded the old model, please re-download the "fixed" one, it did not cut right for me before, so I uploaded one I tweaked so it works. :) You may want to print the barrel and handle separate if you want it to be full size.
