Today we have an SD Gundam of GAT-X105BFP Build Strike. If you watch the anime then you’ll know this one.
So I can’t find this model on Gundam wikipedia, but it is an official gundam in Build Strike anime.
It’s also being sold at hobby shop so it does exist . However there’s not much detail of it that I can find.
This SD gundam model requires 7 sheets of paper to build. The difficulty level is medium and that’s pretty easy for a gundam papercraft.
Template is in PDF and so is the instruction guide so make sure you have a PDF reader.
