The Ray Gun Projects' dream prop the Wunderwaffe DG-2 December 31 2020

The Ray Gun Project is a prop-making service founded by Andrew Lamson. He focuses on giving people the tools and education to make the props. In this project, Andrew tackles one of his dream project, the Wunderwaffe DG-2.

When Andrew first started to make 3D printed props, the Wunderwaffe DG-2 from Call of Duty: Zombies was his dream project that he initially deemed impossible. As time went on and experience snowballed as he couldn't just shake the idea from his head, he slowly found himself working on this complex project. "At first, I started solving the design problems in my head and eventually started solving them in my 3D modeling software," he says. "I've always wanted to see a Wunderwaffe prop replica that could emulate the game's reload functionality." 

Every project is only as good as his reference materials. Andrew was fortunate to get his hands on the original in-game model, which helped get the tiniest details in. Then the tedious modeling process could begin. Once all the features were modeled, he could add, split, and edit all the features and parts for 3D printing and assembly. After an initial pass, it was time for prototyping on the moving mechanical parts. As Andrew tells us, "In this project, I had to create an ejection and reloading system with very small parts and delicate electronic connections. This was the most brain-bending part of the process, but definitely worth it." All the parts were printed with a combination of PLA Extrafill Traffic Yellow, Luminous OrangeRapunzel Silver, and Traffic Black.

To create a seamless appearance indistinguishable from the in-game model, Andrew had to tediously sand and paint every part, which was the most time-consuming part of the prop building. "I spent the better part of 2 weeks meticulously sanding each part smoothly. While it was a bit soul-sucking at times, this was also worth the effort," he tells us. "After everything was printed, sanded, painted, and electronics installed, I assembled the finished Wunderwaffe DG-2 replica."  

One of the most challenging things about huge projects like this is keeping focused on the task and fighting through some building parts' tediousness and monotony. All makers know this natural flow of the making process that starts with excitement and anticipation then slowly fades into drudgery. Gladly this process can also become a learning experience, as Andrew says. "This project taught me how to accept the process making and fight through to the end, where there is joy and a sense of accomplishment." If you feel like tackling this project on your own, you can find the model with instructions at MyMiniFactory or at

"Fillamentum makes some of the best filament in the business. PLA Rapunzel Silver, in particular, is one of, if not the best metallic PLA out there. The layer consistency and precision I can achieve with Fillamentum PLA is invaluable. One of the parts of this project involved several 38-degree overhangs stacked on top of each other, which printed flawlessly. I give a lot of credit for this success to the quality of Fillamentum PLA Extrafill," says Andrew.
