UPDATE: After a few months of testing with this design, I found that the original design was very weak. Thus, I remade this thing using the Dual Angled Rail by T-san, which is itself also a remix of the Dual Picatinny Rail, but using full-length teeth for strength. I also improved the fitment of the rail onto other rails by buffing up the female part of the rail at the bottom.
This is a remix of harddrv1's Dual Picatinny Rail. I extended the length to 10cm and added the third rail on top while retaining the screwports. I raised the middle rail because I was concerned you won't be able to use all three rails together, but I'm not sure if that's enough. I did lose the logo though. There was nowhere else to place it.
There are two variants to the model:
- One has the center of each screw hole 1.75cm from the nearest end. This was the original distance of the holes from the first design
- One has the center of each screw hole 1.5cm from the nearest end. This is for compatibility with Worker (Nerf accessory brand) mounting holes and picatinny spacing.
Feel free to give your comments, especially about usability and practicality.
