This fan-created mobile suit is based upon the classic MS-18E Kämpfer (or MS-07 Gouf) for the Unicorn Gundam timeline. It is called Gundam papercraft Yams 130b Greifer .
This maker of this papercraft is Kyuri, a papercraft designer from Korea.
What’s exceptional about this Gundam papercraft by Style-S is the attention to detail. From conceptual sketches to 3DCG models to background information to scratch-built armor and LED detailing, the guy has covered it all.
I went and look for this model and found one website selling 1/100 resin full kits at the price of $77. The shop situated in HK and its original price in HK is HKD 600.00. Not many sites are still selling this, I did saw one in Ebay but I won’t trust that. If you’re interested with this model you could get it from gkgundamkit.com.
Or you could just download templates kit below and start papercrafting ðŸ˜› Be reminded though that this is crafts for adults so the difficulty is high. Download all parts and extract with Winrar.
