This prop is based on the one used by Dr. Song in several episodes of Who. It has no trigger, so can be taken into most convention halls as a costume prop with no problem.
This prop is ready for photos. The clean and assembled print has been sanded, painted, weathered, and sealed for durability. Clear resin is added to the bottom piece to mimic a flashlight lens.
Final photo shows a scan of the original prop as seen in reference books.
The gun was designed in CAD software and is 3D printed. River Song's Blaster by metaform3d is used with permission under the Creative Commons - Attribution - Share Alike license. Additional details were designed in-house by Cosplay-Senpai
