I heard that the Build Gundam MK-2 was originally in Titans colors, so I wanted to make one using the MK-2 I made recently and the Build Booster MK-2 that I had bought and assembled on a whim, even though I didn't have the main body... but I didn't have the Air Master antenna, so I thought I'd just attach it as is. But when I tried attaching it, it was subtly, somehow, missing! It was missing, so I didn't even take a picture!
So I rummaged through my parts box and found the binder from Option Parts Set 17, so I started working on it. I cut the dowels circled in red and roughly cut the 3mm shafts in half.
