Maybe I should put this in the front, but I'm not going to make a lot of money on this, only a couple of dollars as a gatekeeper to stopper people from abusing model by reselling what essentially free items. Hope you understand.
This is a passion project, I couldn't afford the original YF-21 when it was released, frankly didn't like it enough to stretch, but like a fine wine, it has grown on me, and when I wanted it, it has grown out of my reach. Even though, after years of search, I acquired the reissue, it lacks the Fastpack and short of one Gunpod. So I decided to make my own.
With many help from online communities, reference images or the original parts were shared and information was exchanged. Last year I purchased my very own 3D scanner, which was a formidable addition to my tool kits. From there, it only took an afternoon to make the parts. And two prints to solidify the design. Its not a one to one copy of the original, but it fits just fine.Here are a couple of videos I made to demonstrate the assembly and finished parts.
