Derringer 357 (fixed for printing)

thingiverse

I'm deeply impressed by the model's original designer, who deserves a huge round of applause for doing most of the heavy lifting on this project. I printed it out, but unfortunately, I ran into some significant issues along the way. The complex nature of 3D printing is what led me to believe that supports should never be necessary - and if they are, it's a clear indication that the design could use some creativity. Unless, of course, you're going for a hyper-realistic look. One thing I noticed right away was how much this model lacked ergonomics, which is essential for a prop of this design. So, I fired up Fusion 360 and set out to make the model printable without supports and more compatible with lower-quality machines - and I had an absolute blast making it look cool. To achieve this, I added a few clever extrusions and a ton of fillets. UPDATE: 2/22/17 A trial print revealed that there was insufficient tolerance between the barrel and trigger assembly, no rear sight, and no trigger. New fixed .stl files have been added, along with an all-new render! WARNING This prop is strictly non-functional and should not be used as a weapon under any circumstances. Post-Printing Assembly Tips Assemble this prop using 3 M3 screws (1 x ~5 mm and 2 x 10 mm), and secure the grip panels with a bit of hot glue or your preferred bonding material. Two M3 screws will help mate the trigger housing to the grip, while one M3 screw (or some hot glue) will attach the trigger to the trigger housing - optional, but effective nonetheless.
