I really like the design of the chase/CJ mould and its transformation, but when it came to Prime Cliffjumper his single gun was not enough, so I modelled and 3D printed a more accurate tri-barrel gun from the show: It took me some tests to figure out the tolerances but mostly to see how did the stock gun stay onto the hand, which was thanks to the moulded thumb. Each barrel is 3mm to fit blast effects, but I made the gap between them big enough to fit the 5mm effects if you want some extra bang! I filled the gap between the top of the gun and the arm door kibble with a tab that can be used to put the guns onto the car bonnet, if you want some alt-mode storage. Files are available on Cults, and for those without easy access to a printer I've also printed a batch available for sale!
